As a rabid fan of the game this has to be the most unwelcome film I've seen all year. It actually follows the game to a degree for the 1st 45 minutes, but then spins-off on some bizarre witch-hunting thing before ending as a cheap Hellraiser knock-off.
*Why hasn't the cop aged in 32 years?
*Why did Sharron even come to Silent Hill? The movies seems to forget its own plot by the end.
*Lets put some grey facepaint on a 25 year old.... Viola! a 65 year old woman!
Visually the film does so much right (The ash, the fog, the 'dark world'), and the musc is spot-on too, but then its got some really bad CGI, and the nonsensical story (The game wasn't Shakespear but it made sense). Pointless gore, and a really stupid villain (I'm evil!, I wear a blue dress!, I somehow inspire fear even if an 8' tall guy with a pyramid for a head does a much better job!).
Lotta good subwoofer tho' .... maybe too much......
In summary: a disappointing thumbs down. If I had never played the game it would still be just another creepy movie that falls apart in the last 30 minutes.
