The entire series, while not the best in terms of control is some of the most unique survival/horror gaming ever made. Resident Evil is a bit more action-oriented, but Silent Hill has always had the best plotlines and the best, most intense imagry.
I can't fucking wait to see this. If they did the whole Silent Hill legacy as a series, assuming it's succesful, that would rule.
Silent Hill 4 might not work out to well, but 1-3 would definately be good.
My roomate bought #3, said "Play it alone, w/ the lights out." Quite and experience. I went out and bought 1 & 2 used the next week.
This could turn out poorly though; traditionaly video-game-to-movie adaptations are very disapointing (again, Resident Evil is a perfect example of what not to do...). Keeping my fingers crossed!
