    Don't believe the hype: Paranormal Activity may be a lot of things, but the words "scary" and "movie" are not among them. It is instead nothing more or less than an excruciatingly tedious YouTube gag cleverly marketed to go viral in the broadest and most box office-friendly way.

    Oren Pelli's "Paranormal Activity" is a decent movie in the 'scary' category, but a fantastic one in the 'psychology' category.

    This review contains spoilers, click full review link to view. This movie is okay, not "the scariest film I have ever seen" but, the end where the body flies to the camera did make me jump a little. But, I wouldn't really watch it unless someone made me.. Full Review »

    Couple have weird goings on in house, decide to set up a camera to capture odd happenings on film, lunacy!
    Hand-held camera jump fest which
    doesn't add that much in the way of originality to the genre.
    One or two scary moments but let down by silly stuff. If I heard a massive noise downstairs in the middle of the night,the first thing I'd grab wouldn't be a video camera & then continue filming whilst my girlfriend went bonkers.
    Thought the ending undid a lot of the work & tension that the rest of the film had built up. The alternate ending, albeit a lot more blunt, fitted better.
