So I was super excited to see this movie, I was really upset when i saw it was a theater release until recently. I'm pleased with the way the film was done. If you consider the first 4 mins of the movie think about why he was doing what he did. There is reason behind it in his mind you just need to break down the actual facts behind him losing his mind. Russel did a fantastic job with this character and I felt that I was on the edge of my seat the whole time. You start with a bang and you end with a bang.
