This low-budget horror film was shot in a pseudo-documentary style. Its creators didn’t really hope for huge success, after all, the genre isn’t something a lot of people like. The production was very simple: all the shooting took place in the director’s house and only lasted for 1 week.

But it was the pseudo-documentary style that made Paranormal Activity so thrilling. The seemingly simple horror film earned a ton of money and a lot of respect. As this review says, “Paranormal Activity is one of the scariest movies of all time. YOU WILL BE AFFECTED as it’s hard to ignore the imprint it leaves on your psyche. You know it’s fake, and yet, you can’t shake it. Nightmares are guaranteed.”
