Gore fatigue and random switching character focus near the end

Rating: 2/10 (3 May 2013)

I liked the start of this film a lot, ratchets up the tension nicely, had inoffensive and bland central characters ,a drug abuse sub plot ,and two estranged sibling trying to bond.As the gore hits the fan and things start to fall apart the movie shifts focus on to the brother and his struggle to keep alive until ten minutes before the end when we write him off and switch back to a suddenly ,and stupidity, cured sister whose spent most of the movie as the evil killer bitch in the cellar.now we're supposed to cheer for her survival as she previously slaughtered most of the cast??Sorry thats not how movies work ,you cant get audiences to invest emotionally in characters like that .FAIL
