Oh you all post so much description...
Silent Hill: Wasn't as scary as i predicted. there were some gory, and wierd bits... but nothing especially scary, only the odd jumpy bit. The film is basically about a girl who gets stolen by loads of wierd creatures, and her mother has to go save her. Lots of gore and wierdness, and generally a good film.
I'd give it a 6.5/10, as i said, could have been scarier.
