Chaos Theory (2007)

This movie toes an odd line between black comedy and serious drama, and it never seems entirely sure which side it wants to fall on. Somehow in spite of all this it managed to be very entertaining, and I found myself enjoying it, even if I wasn't sure I was supposed to. In the right roles, Ryan Reynolds is charming, and I've always enjoyed Emily Mortimer. Nothing deep here, but it's enjoyable. 3.5 stars.
