Thanks to its unique shooting style and plot, one of last year's biggest surprise hits, Paranormal Activity, should have been a one-and-done deal. Luckily Paramount decided to give the concept another go-around and found director Tod Williams and writer Michael R. Perry, two guys who really knew not only how to keep the story alive, but expand it in a manner that introduced new elements while keeping the old firmly intact. Think this will be just a studio fast track effort to make bank on a stellar concept? Think again. Not only is Paranormal Activity 2 a well-made sequel, it's just as good as the first.
