Pulp Fiction
I remember first time when i watched this i was absolutly traumatized. This movie is geniues in so many ways. Humour and soundtrack is great.
I like how Tarantino divided the film into several stories and played with its timeline (but in way you can understand the order in which the events happened) and how those stories were from different perspectives of the characters.
Also, like that christopher walken also appeared in the movie, he plays an unimportant role but he absolutly nailed those few minutes. I like how in that monolouge he changed his tone from serious to goofy.
