If you are tired of zombie films you are tired of life.
I rented from Itunes the film helldriver. My one sentence review of the film is "what the fuck". The film is so extreme. It starts with a guy on a wall decapitating zombies for a little horn on their heads. And things get weirder. There is just so much blood. The actors are playing straight as well. Given this is from Japan, there is non of the cartoon like stuff that there would be in a US film.
There is just something so sexy about a woman holding a chainsaw.
