Napoleon Dynamite
Absolute miracle movie. Nothing like this has ever been made since or will be again. This captures a sense of awkwardness that both feels painfully real and very surreal. It has a great aura of warmth that makes it a really great comfort watch. Insanely memorable but still so funny on rewatch. The fact that this was so popular and beloved probably was very influential in the way awkward and surreal humor became so mainstream.
