This movie is under the Horror category. Paranormal Activity has three movies out, and they are working on the fourth one which should be coming out sometime soon, i believe. I have watched these movies numerous times. I like movies that can make me jump. I love the thrill of horror movies. These movies can make you jump quite a bit. To summarize all these movies, they deal with something paranormal which is unknown as to where it might come from. Two generations so far have been struck with this activity. In the first paranormal it was a sister/daughter. The second it was the other sister/daughter. In the third, it happened to be the parents of the two sisters who were shown in the first and second movie. Paranormal Activity went backwards as to when it happened. I'm curious as to what the fourth one may be about, but until then, this is what Paranormal Activity 1, 2, and 3 are about.
