Blurb Movie Reviews - 'Silent Hill'

WTF? If you haven't seen the movie yet, don't read on. Spoilers.

I consider myself a pretty smart kid. I get 'M Theory', and can think in abstract association, but what the hell is up with this movie?

As I take it, it's about some girl who was killed by a bunch of religious freaks. Only she doesn't die, yet she gets revenge on the religious peeps.

But is she dead or alive?

And why did the blonde chick adopt a ghost?

Seriously, if anyone can explain it to me, that would be great.
