Though it may have been released in 2009, Paranormal Activity was actually filmed in 2006 (something reflected in on-screen text in the film itself), an entire decade ago and a year before the first iPhone was released. Imagine how much technology has changed in the years since then. Everyone's got a portable camera/computer/entertainment system residing in their pocket now and entire films (like Tangerine) are filmed on people's phones now. Analyzing how much technology has changed in the epoch since Paranormal Activity was filmed provides a lot more entertainment than the movie itself, which is just disposable horror fare at the end of the day.
