I've had some less than flattering things to say about found footage in recent years, calling it things like "the worst of today's low budget Hollywood filmmaking" and "a thing that shouldn't exist anymore." So let's all take a moment and marvel at the fact that in the new techno-horror flick "Unfriended," the found footage-esque visual gimmick not only works, but it's the best part of the movie. The result isn't much for scares, but it is scarily entertaining.
