Very well acted, very well scripted comedy that has its serious side as well. Although the title suggests it's mostly about sleepwalking, it is actually mostly about the vagaries of relationships, and why they do or don't work. I would like to have seen a little more about Matt's mindset in not wanting to commit to his girlfriend, despite having been with her for eight years. She is the "good" character in this movie, and I couldn't see anything in her that would make him not want to marry her in a heartbeat. Perhaps a little more about why she would want to stay with him, as he was neurotic, came from neurotic parents, etc. Great featured performances by Carol Kane and Kristin Miliotis (lovely to see her in such a different role from her role in "Once" on Broadway). I thought that James Rebhorn was good as usual, but he was directed to be too one-sided. If he were really that p.o.'d all the time, I think he'd have a heart attack! All in all, I highly recommend this movie and am glad I saw it.
