I don't get it

Rating: 6/10 (27 August 2006)

The movie was quite enjoyable as far as a horror movie goes but I didn't "get" it.
I only realised reading the reviews here that it was based on a video game.
The ending left me with more questions than answers.
I kinda felt like the script had been written by someone on acid as I didn't think it flowed very well and there were no explanations for why the husband was seeing a different "Silent Hill" than the wife/daughter were.
A bit more background on the town would have been nice too.
And the ending? What was with that? Was that done to leave the door open for sequel or what?
