Kill List starts off as a relationship drama then soon morphs into a British gangster film following the antics of two hitmen as they cross names off of their "kill list." It's gritty, violent and well-acted. If that were all that there was to this film that would be plenty. However, there is more to the story which is best if I didn't spoil it here. Let's just say that this is an anti-hero version of this classic film (click/hover the link at your own major spoiler risk).
