Rating: 9/10 (23 April 2006)

why were they in a deferent dimension?Were they dead?In the end of the movie the burned girl did not kill them or did she.Or was the mother and daughter already dead in the first place,to begin with?At the final end of the movie.the sky was still raining ashes even out side silenthill. The mother called her husband.He received the call but only heard a bad reception on the other line.once she arrived home. She parked her car in the drive way and entered in the living room at her house.and no one is in the home. but reality her husband was asleep on the couch.It was still raining ashes in her world ,but in his world it was clear as day.he felt her presence and look out side no car was in the drive way.Was she dead?then how did they die if the reaper supposedly spared them.
