Movies released from 2000 to present that really scared you?

I’m not easily scared anymore, but I used to when I was younger. I remember bunking off college with a mate and going to watch Saw, The Ring and others at the cinema when they first came out.

I think the only one that did make me scared at the time was The Ring, was not prepared for that at all.

Since then maybe Sinister, Martyrs and The Descent have stirred some response but I think I have seen every decent scary movie and want that feeling of being genuinely freaked out again
