I'm afraid I was also not a big fan of this show. I hadn't seen a Stro show before, but I do like big song and dance numbers so I was pretty excited. And I didn't think the multiple storylines in Jagged Little Pill were as bad as everyone else thought so I figured I had a decent shot at liking the different storylines in this show. Alas, this was not the case.
I think what JLP did that worked for me was that all the stories tied back to the Healy family. And yes, the storylines in this show do eventually intersect, but the first transition to Mateo's apartment seemed pretty random (Alex Mann at least had the benefit of being associated with Madame Veltri, who is Jimmy and Francine's landlady). And as the show went on you could see how they would eventually become intertwined, but they also had small teases of other moments that were of the blink and you miss it variety, which didn't feel like it added anything substantial and were only included in the name of character development, but were so sudden it didn't actually feel like it added much.
I think the worldbuilding overall is what this show struggles with. There's a bit of a conflict of how much it wants to show New Yorkers as a whole and how much it wants to focus on individual people, and because of that, the characters get a little short shifted and certain lines are tossed in where they would've made much more sense if they came earlier to establish that character or in a show that wanted to focus on the individuals more.
Jimmy's character is slightly more interesting just because they give him a backstory. He's an alcoholic but there's a reason for that, not that they're willing to go into it beyond one line of dialogue. And he's rude to his employers because he has an elevated sense of self-worth that also has to do with his history. But the book seems to shy away from digging into the pathos of its characters (Francine's father gets an off-hand mention, never to be brought up again). I think that's part of where Bandstand succeeded where this one didn't. Then again, Bandstand was trying to be a different show than this, but that begs the question of why they'd bring up these character beats if they're not willing to use them.
That being said, I think there's a lot to like here as well. A lot of flashes of inspiration happen, but unfortunately don't stick around for long enough. I think the most interesting scenes actually had to do with the rest of the New Yorkers and some of the transitional scenes, like the steel beam tap number and the opening and the rain number. I think I actually would've preferred this more as a revue exploring the different walks of life in NYC, with maybe just the Jimmy/Francine number as a throughline.
I actually also found Emily Skinner to be off in some way. She just didn't seem to quite fit into the role for me, and I had a hard time believing her to be what the character was. I think it was something about her delivery of the lines, but it just didn't click for me (and I did think her storyline with Alex Mann was probably the most expendable). I feel like they probably trimmed Mateo's section as well, as I don't think his father spoke at all today? But some of the domestic violence seemed to come out of nowhere without a lot of setup so maybe that was to the detriment of the story overall.
I think the show does feel a bit like what it would be if someone was given a vague idea and told to write a jukebox musical with some lesser known Kander and Ebb songs. A lot of songs are here and gone, without the show really seeming to give them time to breathe. Marry Me was a big one that felt this way, though this might be because I was so certain that Happy Endings would be the act 1 finale and then there were two more songs after that. Quiet Thing also felt a bit dropped in, as well as both of Madame Veltri's songs.
Anyways, I think the show is still worth a watch, but I'd rank it near the bottom of this season's new musicals (along with Almost Famous, which I found inoffensive, but bland). TDF put me in the last row of mezz, which was a surprisingly good view, nothing blocked by the overhang and I could almost make out the details of facial expressions.
