Definitely, Maybe (2008)
This is pretty good, but I had a surprisingly violent reaction to something in one of the special features. The director or writer or someone was talking about the movie (you know that every movie is special, right, and deserves its own thoughtful discussion about how they came upon their wonderful idea, how they found the perfect actors, etc.), and he said, "We wanted New York to be a character in the movie." I suddenly felt the urge to yell "Shut up!" and throw a pillow at the TV. Like 2/3 of all movies aren't set in New York!* Yawn. Or commit violence with throw pillows. Take your pick.
It was original as far as romantic comedies go, and the backdrop of the Clinton campaign and administration was pretty interesting. I had some problems with the movie (not just with the special features), but I think they might be considered spoilers, so I will leave it at that.
