SHORT TAKE:
Simultaneously a sequel/prequel to the first movie as Sophia and we, the audience, find out the details, in flashback, of how Donna got into her self-inflicted predicament.
WHO SHOULD GO:
If you're a mature adult – sure. Go! Enjoy! But don't take the kids. I really wouldn't, personally, want to explain to my child why Donna didn't know which OF THREE MEN was her daughter's father.

LONG TAKE:
You're going to need a scorecard to keep track of this one.
As much as everyone praised the first Mama Mia, let's face it – the story lionizes a promiscuous, irresponsible woman whose only real virtue – granted it is considerable – is that she did not, even for a moment, consider murdering her baby. This one details how she met the three men who became candidates for father. I'm ashamed of myself – but I loved it.
Imagine a two hour music video of ABBA's greatest hits performed by Academy Award winning actors, James Bond, an Avengers regular, a rock and roll icon, and an Untouchable. Don't hurt yourself thinking too hard … all you have to do is go see Mama Mia! Here We Go Again.
Mamma Mia Numero Uno was a movie, 
based on a play, created out of wholecloth from the songs of ABBA, 
a Swedish pop band with hits like "Dancing Queen" (Yes – ABBA is the guilty party), active from 1972-1982. Much like The Who's Tommy, the story 
Mamma Mia was cobbled together from tying together the threads of the band's hit songs, themes and lyrics. 
The FIRST Mama Mia tale is told of Donna who gave birth to a daughter and raised her alone, on a Greek Island, while running a villa. Sophie, the daughter, now a grown women and preparing to marry, wants her father to walk her down the aisle. 
She finds her mother's diary and discovers there are THREE candidates. Without telling Donna, her mother, Sophie sends invitations to all three men, signing her mother's name. If it sounds like a Mozart Opera Buffa, you'd be right. And despite my better judgment I really enjoyed the first installment.
After all, 
Pierce "the BEST Bond" Brosnan, 
Stellan "crazy Avengers scientist" Skarsgard, and 
Colin "Kingsman, King's Speech and Importance of Being Ernest" Firth are the three men. The music is ALL ABBA, ALL the time. AND 
Meryl (can play pretty much anything) Streep plays 
Donna, the indecisive lady … correction … woman in question. The singing was terrific, the dancing joyous, the colors bright. It's a feel good movie —– until you consider the foundational premise of the first movie is that of a woman who has three men —- THREE MEN —- in such a short span of time that she does not know who the father is. I mean – come ON – she would have had to…within merely a couple of days, HOURS! – with THREE different guys – and she only MET two of them the SAME FREAKING DAY she became .. friendly! There are professional ladies of indeterminate virtue who are more discerning than that. ARGH! 
Penny on The Big Bang Theory wasn't THAT slutty.
BUT – if you can put the main character's immorality aside, the original Mamma Mia IS a lot of nonsensical fun as songs are belted out, romances are rekindled, laughs are had and there's a marriage at the end – though not the one we started out with, as the daughter wanders off to start the whole series of mistakes over again. (frustrated *sigh*). Really!?
HERE BE SPOILERS AHEAD!!! I TRIED TO DO THIS WITHOUT SPOILERS BUT IT WAS POINTLESS, SO ——- SPOILERS!!!!!!!!!!
Which brings us to the sequel Mama Mia: Here We Go Again! Donna is dead – to begin with (apologies to Dickens). Little Miss Sophie has FINALLY gotten around to getting married … and is now pregnant. Donna has been dead for a year and EVERYONE converges back to the island to sing all the hit songs ABBA wrote which did NOT appear in Mamma Mia! number one, WITH the addition of 
Cher AND 
Andy "Untouchables" Garcia. The set up is patently unfair. To paraphrase Marlon Brando's Godfather Corleone, it is an offer I just can not refuse. More equitable to ask me to evaluate, objectively, an ice cream Sunday with Hershey's syrup, sprinkles, whipped cream AND mini M&Ms on it. I do not see how I could possibly NOT like it.
If nothing else, this movie carries some serious casting pedigree. Because half the movie is flashbacks, most of the major characters are played by two people each – the younger and the current. So let me help you out:
Pierce Brosnan plays Sam, the second of the three and the one who Donna eventually marries in the first Mamma Mia! Brosnan, along with being more Bond than even Sean Connery, has a varied resume including the lead in the very popular 1980's TV dramedy Remington Steele, reworked the Steve McQueen part in the latest Thomas Crown Affair and was the target of Robin Williams' foil in the blockbuster comedy hit Mrs Doubtfire. The character of Sam, as a young man, is portrayed by Jeremy Irvine – which is REALLY odd because 
Jeremy Irvine ALSO played a younger version of another member of the Mamma Mia! Here We Go Again cast, Colin Firth. Irvine was the 20 year old Firth in the World War II drama The Railway Man. I do not know why they did not choose Irvine to portray Firth in Mamma Mia! Here We Go Again, but they did not.
The honor of playing Mr. Firth as a younger version this time went to Hugh Skinner, "suitor" as it so happens, number one, as a … pity romance. Skinner is notable for playing one of the barricade boys in Les Mis. Colin Firth meanwhile is ONLY the man who won the Best Actor Oscar for his stunning performance as King George VI in The King's Speech, not to mention stealing every scene he is in, in The Kingsmen semi-parody spy movies, Mr. Darcy in the EXTREMELY long BBC version of Pride and Prejudice AND one of the leads in the wonderful send up of The Importance of Being Ernest.
Then Skellan Skarsgard's youthful doppleganger is played by Josh Dylan who, aside from a small part in Allied, is fairly new to the acting scene. He is "date" number three. Along with being one of the Avenger scientist side kicks, Mr. Skarsgard has also been Bootstrap Bill in the Pirates franchise, a baddie in the Branagh Cinderella opposite Ms. James, and a friend of Firth's Eric in The Railway Man.
Lily James (Branagh's Cinderella) is the early incarnation of Meryl Streep's Donna. Meryl Streep is an icon of the acting business. Chamelon-like she has done everything from the Holocaust survivor tragedy of Sophie's Choice to the wildly eccentric comedy, undead evil heroine in Death Becomes Her. She can sing, dance, and like Dustin Hoffman does not shy from looking really ugly, if necessary for a role. And I bet I know something even the most ardent Streep fan does not. Guys and Dolls, the famous romantic comedy musical about a Salvation Army leader, Sarah Brown, who goes toe to toe with a gangster, Sky Masterton, was based – before Damon Runyon took credit – WAAAY back on a 1929 musical play by Bertolt Brecht called Happy End. 
A 1977 production at the Chelsea Theater in North Carolina featured Meryl Streep in the role of Sister Lilian, the original name for Sarah and Bill Cracker, who later morphed into Sky, was performed by none other than 
Back to the Future's Christopher Lloyd. Just in case it comes up in a trivia game……..
Christine Baranski (Leonard Hofstadter's 
blunt and intimidating, emotionally unpresent mother in The Big Bang Theory) is the older version of Tanya and Jessica Keenan Wynn the younger Tanya.
Ms. Wynn needs a special shout out right here. If her last two names Keenan Wynn, ring a bell, it is because she is the fifth in a generation of actors and the granddaughter of THE Keenan Wynn. Keenan Wynn's rich and varied 44 year acting span included everything from 
the early 1960's TV show The Untouchables to 
Stanley Kubrick's Dr Strangelove or: How I Learned to Stop Worrying and Love the Bomb to 
The Twilight Zone and 
Disney movies. And if that's not enough, Ms. Jessica's 
GREAT-grandfather was 
Ed Wynn, who you might just recognize from 
Twilight Zones and as 
Uncle Arthur in the ORIGINAL Mary Poppins.
Harry Potter's Mrs. Weasley aka Julie Waters shares the character of 
Rosie with Alexa Davies.
Meryl Streep reduces Donna's part to a supporting role. This is the first sequel Streep has ever agreed to, so ANY appearance in this movie is of note. She comes on, near the end, in one of the most touching scenes you can conjure. (See below for my list of favorite moments.)
. 
Amanda Seyfried (Les Mis) plays Sophie, the girl with THREE Dads, and Sky, played by Dominic Cooper (Howard Stark in Captain America), is her husband.
Andy Garcia, who I will always remember for his acrobatic, athletic and amazing save on the steps of a Chicago staircase in The Untouchables, plays Fernando, the manager of the inn Sophie now owns. Garcia is actually a musician in his own right, a bongo and guitar player who gratefully and openly thanks America in general and Miami in particular for all the blessings bestowed on his Cuban-origin family, at the Cuban music festivals in which he plays and sings. 
And if you know anything about ABBA music (which you must if you want to see this movie) then his name alone give you a MASSIVE hint for his presence in this movie.
And then there's Cher who plays Grandma Ruby. At 72 years old she continues to have a powerhouse voice. Her roughly 53 year musical career started in the 1970's as the Cher part of Sonny and… which produced the hit Sonny and Cher Comedy Hour when I was a kid (note the song that haunts Bill Murray's Phil Conners in Groundhog Day is 
"I Got You Babe" – their break out hit). She moved on to the quirky rom com 
Moonstruck with Nicholas Cage and the heartbreaking 
Mask to the suspenseful whistleblowing 
Silkwood also with Meryl Streep. Her hit songs include: "Gypsies, Tramps and Thieves", "The Way of Love", "If I Could Turn Back Time", "Half-Breed", "Believe", "Bang Bang (My Baby Shot me Down)", "The Beat Goes On", many of which she performed with Sonny Bono.
And now that we know WHO we are dealing with in Mamma Mia! Here We Go Again, the premise is quite simple. Sophie and widowed Dad are restoring Donna's villa into a premiere hotel. Switching back and forth in time, 
we also follow along as Donna the Younger sleeps her way to and through the Greek Island, eventually getting pregnant with Sophia and decides to stay.
But the sheer jubilance that pervades the movie is irresistible. 
All practicality and common sense aside, this movie has the charm of every enthusiastic "Put on a Show" musical from Shirley Temple to White Christmas. I feel like Tevya. On the one hand the movie revolves around the behavior of a young flighty woman who treats sex like a sport or party favor BUT 
once pregnant she devotes her life to her child. 
There are raunchy jokes and throw away lines but nothing is seen or even acted out. 
A lot of sexually reckless behavior is considered acceptable but both babies – infant Donna and Donna's infant – are baptized in a (presumably Eastern Orthodox since it is Greece) Catholic church before an altar with a crucifix by a cassocked priest, celebrated by the entire town, 
as a ghostly Donna sings her blessing. The plot is threadbare and ridiculous but the song and dance numbers are completely charming and whimsical. 
It is obvious that the storyline is awkwardly cobbled together from the songs and the songs crowbarred into the action but are reworked in creative and appropriate ways as lullabies and nostalgic poetry. Donna was absurdly promiscuous but eventually married, as did her daughter. And as Sophia, herself, points out: "At least this time we know who the baby's father is." That's progress. 
Sky at first contemplates abandoning his marriage for a lucrative job, but quickly comes to his senses and goes back to his wife to fulfill the promises he made to her and assure her there would never be anything more important to him than his wife and child.
MY FAVORITE MOMENTS:
I Have a Dream sung by Amanda Seyfried as she and her Dad walk through the newly restored hotel as we cut back and forth in flashbacks to Lily James' Donna during her first impulsive trespassing tour of the originally ramshackle estate.
Brosnan speak/singing a snippet of S.O.S. as he mourns his deceased wife, Donna, especially considering that he really did lose his first wife, Cassandra Harris.
Sophie singing a duet of My Love My Life with her ghostly/imagined mother, Donna, in the church just before Sophie's baby's baptism. Sophie recognizes in song that Donna would have wanted Sophie to accept her mother's death, knowing the joy and contentment motherhood had brought Donna, and that her mother, Donna, could rest in peace knowing she had raised her daughter well and left a legacy of love.
As to my FAVORITE favorite moments – I went for a matinee but would have paid a LOT more just to see the scenes where Bond, King George, Selvig, Leonard's mother and Mrs. Weasley sing and dance to Supertrooper and Dancing Queen – SO worth the price of admission all by themselves.
Ultimately – despite its flaws it has an undeniable, albeit nostalgic, palpable charm.
