Paranormal activity is ok, at least the first one don't waste time with the rest.
The first movie to scare the shit out of me was E.T. Yeah I know he was a nice alien. But he freaked me out as a kid when they found him in the shed. And then later when he turned white from being sick. E.T. Made little Trey cry.
Modern scary movie to get me was Blair witch. I know right another bad movie to be freaked out by. But I saw that one when it first came out and everyone thought it was real. So it fucked with me.
To tell you the truth I don't watch many horror flicks. I watch em with the chick so she can protect me lol. I can't take em to good she loves them all but things like saw she hates. Saw is just nasty not really horror, seems like that's what horror flicks are now days.
A real dumb one I just saw was human centiped fuckin dumb as shit.
