Mulholland Drive
I think I'm a fan of David Lynch's films, something that makes you really think. Finishing a movie and saying, "What the hell did I just watch?" I think Lynch is taking a dig at the entire Hollywood industry. The movie talks about the dream of being an actress in a critical and surreal way, which makes it seem like a fever dream. It's a film of spectacular quality, and even though when you finish it you are completely lost about the true theme of the film, It's a great experience. That's the point of this type of film: everyone draws their own conclusions about what the director wanted to express. And this is what makes it so special to watch.
