No one's saying it isn't fun. I mean to watch Jennifer Simard belt her tits off to a slot machine and Adam Pascal belt out some rock tunes is totally worth the price of a rush ticket. It's just not great camp. The book is a mess. The second act doesn't really have any "songs" and the staging is messy and uninspired. Songs are sang for a verse just for the joke and then it's blackout, and the actors awkwardly shuffle off the stage, and lights up on the other side of the stage, then the actors push the set back out, etc. It gets tiring.
The set is basically a typical 2 level set. It looks like a cheesy casino, except it's only two large poles with lights, an upper level and a lower level with a curtain behind it that comes in and out. The curtain behind the set rises, and you can see all the set pieces back there waiting to be rolled on by someone, and it lowers again once the set pieces are in place. It's a really ugly and uninspired set design. The curtain is like this really horribly cheesy curtain with like "casino" stuff on it. And then in Act 2 it has like bricks all over it looking like a "disaster." The whole thing looks like it was built so it could be sold to a dinner theater in Florida.
Again, there's a way to do camp and "cheap" on Broadway and still make it inventive and fun, but this just felt like they cut corners all around.
And there are some true funny moments that Jack and Seth have come up with, but they are few and far between, and they don't understand how to keep the momentum of a show running. A zany comedy is tough because you have to keep it so high level all the time. It's how I felt about Something Rotten, the first 40mins are awesome, and then it starts to drag and you get the same jokes, the same shtick over and over again.
