This film had quite a lot going for it. Essentially the same plot as Hostel but with much more believable gore. It also benefits from a quite unnerving main character, excellently portrayed by the actor.
Sadly, the writer and director clearly didn't believe enough in their own movie as they felt it required one fairly graphic sex scene and many scenes set in a strip club that were completely pointless and added nothing to the film.
There are no major plot twists that you can't see coming but it's all put together pretty well. It's just a shame the writer/director didn't have as much conviction in what they were doing as the SFX people, who really did do some top notch work on the gore.
