I'll begin with the title of the movie. Let's just say it's pretty easy to decode/decipher, which makes it kinda painful, that the characters in the movie, don't realise it for a very long time. That's all I'm gonna say.
Having seen HATCHET and therefor seen Ms. McNabs natural and therefor obvious talents, might be a disappointment for those waiting, to be "exposed" to the same thing here (pun intended). But she plays her part very convincing (for a horror movie) and the others don't let her down. On the other hand, the script does let them and the audience down and the "Less is sometimes more" phrase could've applied here too (especially at the end, where it tried to compensate for the lack in other departments, in just being ... out there! Not really bad, but not really good either!
