Just got back from seeing this tonight, and to be honest I'm a little bit disappointed. I didn't really find any of the songs memorable besides the opening number. Act 1 was good, but act 2 felt a little scattered. The story was sort of predictable, although I really liked the overall theme.
The jokes were either hit or miss, and the audience seemed pretty unresponsive throughout. I laughed out loud a few times but didn't find it nearly as funny as Avenue Q or Mormon. The part that got the biggest laugh was the little audience participation bit.
The performances were strong (besides a little boy who I couldn't understand at all and who really couldn't sing), and I thought Betsy Wolfe really hit it out the park! Matt Bittner impressed me too.
At intermission, the people around me seemed pretty mixed/negative about it. With a bit of tightening and revising I think it could turn into a strong show, but I don't see it being a big hit.
