Joseph Gordon-Levitt. Zooey Deschanel. What's not to love?
I liked it - except maybe for the you've-got-to-be-kidding-me ending and the fact that Summer's storyline is a bit um... Nonsensical. Out of character.
But apart from that, I really liked this movie; it's a non-linear story with little bouts of interesting cinematography in-between the major plot points. It's enjoyable, even when you want to tell some characters that they're being real douchefaces.
