    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.

    Admittedly the first parts of the movie were kinda boring. But I can't help but feel it was purposely boring to lower expectations to increase the shock value. Brilliantly made movie, the ending is one that still haunts me even days later and is probably the most terrifying scene in a horror movie I've ever seen. Honestly I can't stand when people act tough and say this movie didn't scare them. Stop kidding yourself. It was probably the best horror movie I've ever seen. And Mike paid $20 for a ticket????
