I adore films that stay in one location and can imagine it's difficult to pull off (but when pulled off well, like 12 Angry Men, it can be magnificent). One location means there is more focus on the characters and you really get to see who is a good actor and who isn't. I thought everyone in this movie was great (especially John C. Reilly) and conveyed their characters believably. The storyline is simple, but it's a joy to watch the two couples' differing views on parenting and marriage.
