The ending (spoilers)
The two getting back together at the end didn't feel earned at all! They both had a few brief scenes of reflection and Mandy Moore see's everyone kissing at the NY's party and voila, it rumbles up her feelings for Martin Freeman again.
Swinging With the Finkels just felt a bit contrived and fake. Also, the swinging element is only a 20 minute segment, yet with the poster/dvd art you'd think it played a much larger part.
