The Five-Year Engagement

Is more of a "problem play" than any other genre, really. It's a romcom, but there's a lot of turbulence along the way. Blisteringly funny though, and full of bit parts for actors that were (or would go on to be) big deals. Also obviously it's a big plus for me that so much of it is set around Ann Arbor. Worst thing is that its second act drags, but there's a great payoff.
