A very predictable and at times drawn out horror/chiller. Sean Bean plays his role very well but (being petty) his accent does start to annoy you.
The film kind of plods along at a random pace which makes it equally annoying as some sequences are really good. The title characters don't have much appeal to them and at times you want Sean to get them first just so you can end the film.
Small casts and slow plots have been proven not to work for horror films and this follows the same route as films like Wrong Turn and Wolf Creek.
Not bad if you're in the mood for something mindless or its the only DVD you own, if you have a choice then probably go for something else more fright worth or entertaining.
