I also saw the show last night, and I was really sad that there wasn't a song list in the Playbill. I only am casually aware of Gloria and MSM's music from my childhood so I would have liked to know what each song was.
**SPOILERS AHEAD**
THE GOOD:
THE BAND! They had 12-15 guys on stage playing the tradition MSM lineup. The sound filled the theatre and you felt it in your guts. Whenever they reenacted concert moments, the lighting, music, costumes, and dancing really were thrilling.
Ana Villafane really embodies Gloria Estefan. Her manner of speaking, her singing, and her look are all spot-on. When the real Gloria came up on stage after the show, I had a "Oh yeah, that's what you really look like" moment.
Josh Segarra plays Emilio as a hero-type with a self-deprecating sense of humor. The scenes with him and Gloria are very sweet and romantic, with a bit of sly humor. I like their chemistry.
Andrea Burns is great as Gloria's mother. She has a scene in the first act that shows her past as a Cuban singer in a bar, and she really tears it apart. I was really impressed at the transition from a overly-protective, conservative mother to fiery Latina performer.
Alma Cuervo as Gloria's grandmother is the comic relief of the first act. She plays the a "Mulan's grandmother" type. Plenty of one-liners and lots of love and heart for her granddaughter. She is the one who encourages Gloria to continue doing music instead of a more sensible career.
I really enjoyed the end of the first act. It reenacts a concert scene right after "Conga" has become a hit. The actors come off stage and grab random people from the audience to form a conga line up the center isle. It was cheesy, and maybe it was just the people who were sitting around me, but it felt very joyous and not as annoying as it sounds.. It was big and bombastic, and it really had me humming on the way to the restroom.
Whomever said that they expected to see Gloria sing "On Your Feet" to the recovering victims of the crash made me laugh really hard. I was expecting something similar, and was happy to see they didn't take that route.
The ending medley of MSM hits "Turn The Beat Around, On Your Feet, Conga, Rhythm Is Gonna Get You, etc" ends the evening on a postive, up-beat note after the downer of a 2nd act.
THE BAD:
The second act was a bit ballad-heavy for me, as it primarily deals with Gloria's estrangement from her mother and her recovery from her bus accident.
There is a slightly odd "Surgery ballet" scene with dancers waving white sheets all over the place. Gloria, dressed in all white, is surrounded by everyone from her life (her younger self, her dead grandmother, her husband, etc) also dressed in white. I didn't recognize the song, but I enjoyed it very much. The scene itself was heavy-handed.
There was another odd transition from a scene in Gloria's physical therapy room where she doesn't want to do the American Music Awards because she doesn't want everyone feeling sorry for her when she's not fully recovered. Out of nowhere, Emilio starts singing "Don't Wanna Lose You." I mean, full-stop, just starting singing. . no intro music or anything. It was jarring and kinda laughable in that context.
Overall, I think it has a life on Broadway and in regional theatre. It's not life-changing by any means, but it was a fun night at the theatre. It wasn't cringe-worthy, and I found myself pulled into the world they were creating on stage. I'd put it up there with Mamma Mia, Jersey Boys, etc. . Tourists will eat it up.
