Vile. Yes, its vile, why? Not because its been compared to other 'torture porn' films (which it isn't), but because its excrement mostly. A group of people trapped in a property of which they decide, very quickly, there is no escape even with multiple instruments to aid them and a lack of logic:'if there is a way in, there is a way out'. The gore is mostly inference at best and the lack lustre sound editing and soundtrack only further mute the need for a viewing of this punk arse bitch of a film. Cliché acts of even trying to review 'character development' would be futile in the least, as for the aforementioned twist at the end (by previous reviewers) there isn't one, you would have to be brain dead to believe the ending was even remotely 'twisted'. This film sucks basically.
