What do you expect from a scary movie?

Rating: 8/10 (19 June 2010)

After seeing so many low rates for this movie, I couldn't close the window of my browser without leaving my review here.
I really can't understand why so many people disliked P.Activity so much. It gives all that horror movie fans want - supernatural, convincing acting, good script and most of all, good thrill.
All right, I have to agree with the fact that the characters sometimes act like stupids along the movie, and at this point, the script could be a bit better, but it's far from taking the credits of P.A. This is still the scariest movie i've ever seen in AGES! Some people say that isn't scary at all, basing its thrill in "cheap effects and noises". Well, if this isn't scary, then what it is?! What do you expect from a "scary" movie? Lots of teenagers screaming in panic, being chased by a guy with a chainsaw in endless gore with bodies spilling blood?!
The genius of this movie is the fact that as a low budget it succeeded where most have failed spending hundreds of thousand dollars - bringing what is most important in horror movies: the constant feeling of tension till the very end. For that reason, I dare to say this movie is even UNDERrated, instead overrated. Seven stars is the least I think it deserves. The hype isn't wrong at all.
The only reason I see to this movie receive so many bad reviews is that people got used so much with garbage that they can't recognize a good movie when they see it anymore.
