I watched this film before and couldn't follow it. There's so much going on, both visually and dialogue-wise. As odd as it might sound for a rotroscopic animation, the movie feels authentic, perhaps because PHK spent a couple of years around drugs.

At its heart, this is a sad story about a guy slowly losing his mind and his life to drugs, and Keanu Reeves does an excellent job portraying this, while Robert Downey Jr is amazing at being the paranoid conspiracy supermind.

Perhaps what makes this story even sadder is the fact that at the end, when we learn who the real villains are, we shake our heads with a solemn of-course. Like other good movies, it offers a bleak look into a future that is not too far from us right now, one that hopefully we won't get caught with.
