An ex & I caught this & we both loved it. We both have been Tom & Summer at a point in our relationships (funnily enough, we both agreed that we werent Tom or Summer at any point in our relationship) twas a refreshing portrait of love, break up, & moving on.

JGL is for sure a leading man, very promising career for him I think. He does sorta remind me of Heath Ledger and I'm not quite sure why that freaks me out a bit but it does.
Zooey is so cute I want to vomit, it's just impossible not to fall in love w/ ol girl whenever shes on the screen. It's an endearing quality but it will lead to type casting I think. People make lucrative careers out of being the ____ actor, so that might not be a bad thing for her.
Sidenote, I really want to hate Zooey in a film LoL, somebody make this woman a villian!
