Hello I am the movie encyclopedia and if no one else will see it, I will.
As many of my readers will know, I loved the first Paranormal Activity. What some people don't know is up until Paranormal Activity I really didn't like "found footage" films. I mean I had seen Cannibal Holocaust (if that counts) and Blair Witch but really I wasn't into the whole idea of home video films. As someone whose done a number of low budget (and I mean like me and a few friends) horror films, I thought that if these kind of films could get released and make millions but ours couldn't it was a bit unfair. But then, after being nagged by my friends, I went and saw Paranormal Activity and I was genuinely unnerved. It made me scared of my shadow. And it took me a while to figure out why. The Exorcist, Dawn of the Dead and The Descent were all scary in their own right but what PA did differently was that it relied on subtlety and realism, something that the aforementioned films don't have.
And since it made a huge profit it was a no brainer that they would make a sequel. But does it suffer from the usual sequelitis that other films tend to have? Surprisingly no. It's not as good as the first one, but it's still damn good.
