What is the most disturbing movie you have seen, or in better words one that had had a profound effect on you including nightmares or flashbacks concerning it.
I'm not sure why but Event Horizon disturbed me alot, I felt the director had gone off on a tangent and what we were seeing was a reflection of his drug induced nightmare in all it's gory glory.
Like some sort of fubar'd mental mind game.
It really did disturb me for a long time after but I'm not sure if that say's alot more about me than it does about the director lol.
I have The Ring to watch next and the g/f won't watch it with me so that could be my next disturbing moment
