(500) Days of Summer is, to be brief, the story of Joseph Gordon-Levitt meeting, kissing, fucking, and continuing to fuck Zooey Deschanel, whilst Zooey Deschanel tells Joseph Gordon-Levitt continuously that he is Not Her Boyfriend. Then she says the fucking has to cease, and she seems not to feel too bad about that, and he is like, “BUT I AM YOUR BOYFRIEND!!!???” And she is like, no you’re not. And then he is sad.
We are encouraged to infer, from this series of events, that Zooey Deschanel is LITERALLY A MONSTER.
