Now that it has been released, can I just say what utter tripe this film was. Biggest disappointent of the year so far for me. The plot was so, so wet, missing the most important ingredient for films of this type... a villan (you cant count that guy with his unsteady hands... after all, he was just a client). No character development whatsoever, and just when you think you've figured out the one remaining guy... he makes a decision out of character - namely going back for the asian chick. If they'd have kept his mate (Josh?) alive, and he'd heard him scream, then that would have made sense. They also missed a trip with that Oli fella - he was really quirky and fun to watch.. and they just remove the guy, without the satisfaction deserved by him.
The whole film rely's on gore to maintain any appeal... and also there it disappoints. It's just too much, pantomime for the most part, and quite laughable.
A couple of good scenes, notably Josh's end (liked the tension built when he's looking around the room through one small peephole), but not enough to salvage the film in any shape. My vote - avoid.
Oh, on the plus side, some cracking norks on display throughout.
