  1. With its this-is-really-happening vibe, Paranormal Activity scrapes away 30 years of encrusted nightmare clichés. The fear is real, all right, because the fear is really in you.

    This is a brutal, exhausting, and genuinely horrifying little ghost flick.
  3. 88
    An ingenious little horror film, so well made it's truly scary.
  4. 83
    The film loses some of its grimy verisimilitude toward the end, but it’s nevertheless a surprisingly effective low-budget shocker with a sensibility as current as the latest viral videos, yet rooted in the suggestive, less-is-more atmospherics of Val Lewton.

    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????

    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 »
