10 Genius Ways Movies Made You Rewatch Them

If The Blair Witch Project pioneered the idea of inviting viewers to catch glimpses of its titular entity throughout a shaky assemblage of handheld camera footage - despite there actually being no visible monsters at all - Paranormal Activity took that idea and stuck it on a tripod.

So much of the original Paranormal Activity is comprised of locked-off shots of strange, possibly paranormal phenomena unfolding in and around the bedroom of protagonists Katie (Katie Featherston) and Micah (Micah Sloat).

As the happenings become increasingly unexplainable, the audience is practically begged to scan around the frame, searching for even the faintest glimpses of the invisible demon interacting with the environment. And this might be the main reason to rewatch the movies, honestly, as the franchise mastered the art of letting audiences do most of the scaring themselves with their own imaginations.

Did you see a shape moving in the dark of the upstairs hallway? Did the bedsheet just move by itself? Paranormal Activity is a brilliant exercise in both economic filmmaking and scoring repeat business.
