Paranormal Activity has become a completely unexpected blockbuster hit. The movie cost a mere $15,000 to make, but has grossed almost $100 million in seven weeks.

Paranormal Activity is about a girl possessed by a demon, which has a striking resemblance to The Exorcist, except the story has a bit of an unexpected twist that has hit a home run with audiences looking for a good scare.

The Fourth Kind is about real case studies where people claimed to have been abducted by aliens, and it seems to be doing fairly well after one week, but it’s far behind Paranormal Activity.

It seems most people like to be scared, and nothing scares them more than demonic possession.
