This is an incredible mash up of a number of different movies put together. I would say that this film is like watching The Texas Chainsaw Massacre mixed with Enter The Dragon with a soundtrack from Suspiria.
The action is fast, funny, slapstick at times. There is gore, there are cannibals, there are beheadings, amputations, weird looking freaks, leather faced maniacs, and a sort of Horror Island location.
All in all an incredible viewing experience for those who enjoy their cinema redder than red.
