Lesson Learned form Paranormal Activity

I saw Paranormal Activity last night and the first half was incredibly boring (and the camera movements made me slightly nauseous) but the last half really freaked me out. I don't know what the filmmakers wanted me to learn from this movie but what I got out of it was that if I am ever in a relationship or living with someone who is haunted by a demon it's best to just cut my losses and leave them. I will definitely not be sticking around to film it.
