I think I've managed to watch every film similar in style to the whole found footage device that's out there. A lot of them come nowhere close to Paranormal Activity in terms of suspense, apart from the obvious ones like The Blair Witch Project and [REC]. One I saw very recently at FrightFest was bizarrely another spanish-language horror film called 'Atrocious'. It's a lot more original than the majority of other POV horror films that are out there and I was really surprised by how many genuine scares there were. A great film, definitely check it out if you haven't heard of it. I think it should be out on DVD soon
