Saw this yesterday, afternoon. It's a good show, but not a great one.
Others have given plot points, so I won't rehash. I saw the movie years ago and I think it's a good story with a lot of heart and not a bad choice for musical material.
There is much to like, but the show needs work before it moves to Broadway, which seems to be the plan.
The cast is uniformly good, save Jason Gotay, who is quite talented, but just very wrong for the part of the older 'C'. Never once did I believe he was living this life in the Bronx. Indiana, maybe. Three of us went and it was everyone's first and biggest complaint. It does impact the whole show and detracts from any chemistry he might have with Jane, the girl he likes. Nick Cordero is very good as Sonny, the gangster and Richard H. Blake is also very good as the dad. Joshua Colley, who plays Young 'C' is outstanding and I wish he had a larger role.
The music is enjoyable and very much of the 50s and 60s style. The dancing is energetic and fun, but there isn't as much as I would have hoped with Sergio Trujillo doing the choreography.
The staging is fine, but just fine. It's evocative of the period, but at times, I thought it seemed a little cheap and sparse. The projections are not intrusive and work well, when used.
This is a 2 hour musical, including intermission. They should cut the intermission and make this an hour and 40 minutes. The second act has only 5 songs and 5 very short reprises of songs from the first act and it shows. The second act is weaker and shorter and should be beefed up a bit, with some continuing conflict, rather than just a tidy resolution of loose ends. Tie the two acts together and tighten up the writing and it would flow well. I did wish they would beef up the mother's character, a bit, but it's not a must, since this is really a father/son story.
Audience reaction seemed positive. It did get a standing ovation, which not everything does at Papermill. I thought it was worth sincere applause, but it's not standing ovation material, yet.
Glad I saw it and would recommend it. Hopefully, they work on it some. It would be nice to see it succeed, elsewhere.
On a side note, this show seems to be pretty well sold out for the run, but the top ticket at Papermill is now $140!!! Holy cow.
