4. 500 Days of Summer (2009)

The main reason I like this film is the stilted way it shows the process of falling in and out of love. The displaced order of events and harshly realistic acting made a film that made me laugh and cry and feel every emotion the main character felt. It was one of the movies that made me want to act and direct or just be involved with making something so amazing and thought-provoking. The director (Marc Webb) is a great director and pulls of the non-linear narrative of the story with such finesse that the movie's not confusing or boring and kept me on the edge of my seat.
