it be an impulse decision and i want a scary movie and i just grab this from the shelf and i be glad i do . it be a long time since i have see a low budget british film that i have enjoy and this come a a pleasant surprise and it be well film but doesn not go down the route of try to be too clever . it just show you what you need to see and avoid most of the gruesome event and instead show you the result . it entertain and suggest and of course scare . if do not have the preconception that you be go to watch an extremely clever horror and be just look for a back to basic horror then you should enjoy this .
