How Paranormal is the Activity?

If you ask people whether I get scared easily, they'd probably say no and be right about it. I mean, sure I scream at the slightest touch of a cat's tail or at the sight of a creeping cockroach or a bulging bullfrog, but when it comes to the idea of encountering paranormal activities, I'm pretty steady. I'm not saying I don't shiver at the thought of it - of course I do, I'm not crazy. I guess I just really have enough faith to shield me from such fears. This faith enables me to rent a dorm room without a roommate and sleep alone in the dark. (But I am extremely frightened of serial killers, robbers, and rapists; just the mere mention of those terms are enough to scare the hell out of me. Oh, and blood.)

So anyway, why am I saying all this? See the poster below, and imagine how freaked out I am - me, who's supposedly "tough and sleeps-alone-in-the-dark-while-fighting-insomnia-at-3-ish-in-the-morning." Could you imagine? 'cause I can't. And wouldn't dare.

Paranormal Activity, an independent horror film by Oren Peli, was first premiered in 2007 at Screamfest Film Festival in the USA, and was released nationwide in 2009. It tells the story of a young couple, "engaged to be engaged," who are being haunted by a ghost in their suburban home in San Diego. To capture evidence, the boyfriend buys a video camera, and starts a three-week long project. The events he records reveal so many strange activities that could only be described as paranormal. A consultation with a psychic ultimately tells them that the girlfriend is, in fact, being followed by a demon, who feeds off negative energy.

Have you seen it already? If you have, please tell me if it's worth watching, and if it really is as frightening as the rest of the world says. I'm a painfully curious person, and would like so much to see this film, but my instincts are telling me not to 'cause I might lose my innate toughness. And I might end up crawling in my dorm mate's bed next door.
