So overall, what did you guys think of Paranormal Activity?

I know alot of people din't like it, but I thought it was amazing. I love a good horror movie, but these days they don't usually truly creep me out. However, this one really did the trick. I think I was so fascinated why this demon was after Katie. That always kept me wondering. What do you think it wanted from her? What were your favorite parts from the movie? Which ones scared you? The parts where the thing was breathing on her, and when she was dragged down the hall was crazy scary! Nothing topped the footprints though.. That was just effing creepy! On the second night of them using the camera was when they heard the huge bang downstairs and Micah and Katie both yelled fu** and jumped up, that was intense.....But the droning noises that the camera started to make when ever the demon would come around was creepy but awesome too. Well, I'm sorry if it seems like I'm ranting but I just wanted to know yalls opinions! Thanks, have a good day!
