Without a doubt, one of my favorite filmmakers working today. He's 3 for 3 in my book and it seems with every film he gets better to some extent. His films are full of emotion. I'm a sucker for visuals and colors and he brings it with every film. I hope he continues to do great work in the future.
I don't think I could pick a favorite because I like his films for different reasons.
Clint Mansell is also an amazing composer that adds layer after layer to the films.
I sadly haven't seen any of his shorts.
