Half a star, but you should totally watch it
This review may contain spoilers. I can handle the truth.
Despite the fact that this film is very well made and acted, I can't think of a British horror film I detest more from the last few years (I haven't seen Zombie Women of Satan). My reason for loathing it is purely political, I don't think I can think of a film that demonises the working class so completely. Every single working class person in the film is a scumbag. This is a bullshit middle class nightmare, and it's no wonder the Daily Mail gave it a five star review.
