The film starts off slow but builds to give the viewer one hell of an ending. I love Guillermo Del Toro's work and one of the only reasons I got this was because of the fact that he produced this I knew nothing about the story or plot before seeing it. I was pleasantly surprised by the result. This is a well crafted, well acted and very well directed horror film. I loved the mood and tone of the piece and thought that the film was well worth what I paid to rent it. As a horror buff I found it scary enough to keep my interest but it wasn't just hack and slash it actually had a decent story and I found the characters very interesting. If you like horror, or foreign films definitley give this one a try.
