Summer is in the title, so yes, "500 Days of Summer" is on our list. Sure, this film has its heartbreaking moments, but the dates that Joseph Gordon-Levitt and Zooey Deschanel's characters go on are worth a watch — and possibly a re-creation with your bae, assuming you want to leave your house, which we would advise against . . . at least while you're in the middle of this summer-movie binge.
