I saw it a few nights ago and I enjoyed it very much. It's not a play that breaks any new ground, but it was interesting/funny and the cast is great. Really good cast. I don't think it will go any farther than PH but it was an enjoyable evening. But I am the type of theatre goer that will try to find the things I like about a show. I saw Significant Other last night and didn't enjoy much of that. The Qualms was much better.
I'm going off my viewing at Steppenwolf last summer. I was kinda eh about the play, trying to be insightful with comtemporary sexual issues, but still pretty slight. In hands of good actors, though, elevated the material.
