That reminds me, one of the things that bugged me about this movie is the way all the people in Silent Hill do the 'rock out' aka devil horns when they point.
I noticed that too. I justed chalked it up to it having something to do with witchcraft and what not. Afterall "rock out devil horns" represent the devil and witches were supposedly in league with the devil so it fits. My two cents anyway.
