Horror Movies

Recently I have been wanting to see a good horror movie, or maybe a suspense movie, I have already seen "Silent Hill" but too much blood, I don't wanna a bloody one, but one that mentaly disturbs you (really weird don't you think so?), but it should be good one. I asked some people wich one should be good they said that "the Ring" or "the Sinister Island" are very good examples, let's see wich one is better. What do you think? Which is better? Or is another one the best?
