There are three main problems with this film. The first is the lack of acting ability from the most of the cast couldn't act their way out of a plastic bag and I'm not just taking a pop at Paris Hilton (who does flakey blonde bimbo quite well- she's made a career out of it).
The second is the story. It's not that the story is a bad one, it could have made a great film, if it had been treated right. It could have been made into a dark, creepy, truly fightening film, but the (very) young producer and director seemed to be aiming for a buddy film feel. Horror and buddy film - they can mix, I've seen some good horror films that have managed it, but in this case, it was a step too far - particularly for such an inexperienced director.
The third problem (and in my view the main problem) is the characters are particularly unlikeable - it was set up at the beginning that they were supposed to be childhood school friends and the only actor that even attempted this portray this friendship was Lex Shrapnel, smiling and joking with the the rest of the cast, while the others managed to pull off an "I've never met you before and I don't like you" position with ease all the way through the film.
I admit that I bought this film (second hand) because I'm a Lex Shrapnel fan and I further admit he's been in some good ones and some bad ones, this has to be one of the worst. He tried his best but was let down by the others, and definitely appeared uncomfortable in the few scene he had with his screen "girlfriend" Paris Hilton and her bad acting skills and bimbo attitude.
One thing in Ms Hilton's favour is she dies well, and in this film she dies early.
By the end I wasn't bothered if any of them survived. There is no twist at the end. It is a very basic film that had the potential to be so much more, what a shame that the director was so young and inexperienced.
