Paranormal Activity 2 (2010) - 8/10
This is as terrifying as the first. As soon as it finished I put every single light in my house on, because fuck the dark. It might be old school scare tactics but it just seems so real. I would put up with shit like this happening in my house for about 5 fucking seconds. Seriously, I'd be out the door and down the road before you could say 'boo', desperately hoping I'd not soiled myself in the process.
