As far as scary movies I rate it on how many times it makes me physically react, in this movie it had me to the point where I didn't even realize my mouth was open until after the scene when it was drying out. very scary! The only part I didn't like was the ending, c'mon really? They ruined it by making it into a stupid myspace forward "Katie's whereabouts are still unknown" left unwritten was "and if you don't forward this on to 10 friends by midnight tomorrow she'll GET YOU!!!" other then that though, SUPER scary! loved it
