Honestly, I didn't mind the show. I have no strong feelings toward it. It was enjoyable at the time, and I did laugh several times, and the audience was really into it (which was nice).
The score is lacking. There were some genuinely crazy/entertaining numbers ("The Girl for You" was insane, but you can't help like it?), but the songs themselves were mostly forgettable.
The strongest selling point of the show is the cast. Zachary Levi does a good job with the couple of songs he has ("In Love With You" was very fun & he dances

) and he is a strong actor, very charming and funny. Krysta Rodriguez was fine - I've never been a big fan of hers, though, so *shrugs*. The rest of the cast (Bryce Ryness, Kristoffer Cusick, Blake Hammond, Sara Chase, and Kate Loprest) were all great playing their various roles - overall, funny.
I can't see this show lasting very long on Broadway, though.
