Its not that gory, but it is cheesy and complete shit. It seemed to be dani filths character killing a bunch of people involved (or their friends/family) in the convcition of his father, some kind of pedophile-hypnotist-satanist. Before the people died however, the movie had stories about some kind of sinful deeds that they committed that led in some fashion to their deaths. Often, filths character was hardly involved at all.
I bet even before I finish writing this marilyn will have posted something about it being the most disturbing and excellent movie ever.
