This film is a bit of a tough watch. It has a decent cast, alright cinematography and some worthy practical effects, but the screenplay just doesn't work, and the director probably had a hard time since the writer is the producer. I know this was initially written as The Hills Have Eyes Part III, I think that script would have been better. There's a lot of references from great films, for instance the antagonist feels like a human version of a xenomorph, which in a way works. There's a line I find funny - the brother says to his sister's boyfriend "You couldn't get a piece of ass if you were a toilet seat". Bro, he's bangin' your sister lol.
