Improvements

I was hoping for a Tarantino type character when I read the description of this movie. I'd advise you don't waste your money, the main character has no depth, no real viable explanation as to any of his actions and is utterly despicable. Maybe had there been a more charismatic or recognisable actor portraying charlie I'd have been a little more drawn in. Instead I practically forced my way to the end of this through a lot of cliches, even more over the top 'look at me I'm a crazy villain' acting and no real inventive or original ideas. What do you guys think could have improved the movie?
