I watched Misery on Netflix. It's not very scary but it's quite violent and creepy?
I also recommend the Terminator films, Mama, and the sixth sense. Not sure if they're on Netflix though.
They're the only ones I've watched cause they're the only ones that I'm allowed to. My Mum skips the 'rude' bits as in... uhh... I don't know how to put it... uhh... 'Physical interaction' (In Terminator 1 only)
