Today is a great day for fans of lights going on and off and stationary webcam footage, for today is the day that the trailer for the new Paranormal Activity has dropped. If you remember, last year, directors Henry Joost and Ariel Schulman went retro and took the series back to the boxy camcorder days of the ’80s, which was a fun way to add some zest to the experience of thinking that you might have seen something move over there in the background for a minute, but then it was gone. Well, this year they’re back in the saddle, directing Paranormal Activity 4, and it turns out they’ve found yet another way to spice up amateur looking footage that leads up to a figure standing behind the main character and then a fade to black: they’ve added video chat. Yes, Paranormal Activity 4 takes the story of haunted sisters Kristi and Katie and brings it back into today’s world. This time around, the remaining family members seem to have moved next door to a teenage girl or something, and also there’s a kid who has electro powers like Powder…but none of that is really important. The Paranormal Activity movies aren’t so much traditional storytelling as they are the crafting of an experience. It’s all about sitting on the edge of your seat, never knowing when something freaky is going to happen next, and then screaming your lungs out when something suddenly does.
