This film was hard work. I get that it's a true story and you have to be somewhat loyal to the reality of what actually happened, but man were these two tedious people to follow for 90 minutes. One is a wimp and the other is a psychopath. A psychopath can be a fun character if written correctly, but this one was just boring. He had nothing interesting to say and when he was killing someone it was just grim.
There were times when the movie showed some promise. I liked the addition of the monkey (sorry, chimpanzee) to the story and the added dimension that brought to the proceedings. Too often though scenes felt very forced and like they were just there to give the film some kind of purpose.
Basically I didn't care. The film never found a way to get me invested. This one wasn't for me. 5/10.
