I don't know why some of these reviews are short-changing the movies for misleading the viewers with trailers. That's what made it scarier. You see a scene in the trailer, and then you see that same scene in the movie, and--in a horror movie, like this--that scene is a thousand times less scary, because you saw it coming and know what happens. For me, sitting there in the theatre and watching the scenes I expected to scare me one way, only to turn around and blow my mind alternatively... Why on earth would I complain about that? Talk about grasping at straws. That's now a complaint? If that's the reason you're bringing this movie down from 5 stars to 3, then for the love of god don't write a movie review.
This movie terrified me. I saw 1, loved it, couldn't sleep. I saw 2, didn't faze me at all. I thought 2 failed in all the ways that 1 succeeded. But 3 surpassed even 1, in my opinion. It was terrifying throughout. You weren't even safe in the day time. It was legitimately scary, in two fantastic ways. First, it didn't rely on gore and dismemberment. And second, it didn't rely on all-of-a-sudden shock-value screen appearance accompanied by a whir of the string section. Those two components typify the modern horror genre--look at Saw, for god's sake--and in my opinion are the joint reason that horror movies are worthless. The PA series shows you how to make a good horror movie. it doesn't resort to cheap scare tactics like slasher films, nor does it simply try to outdo itself by breaking the previous film's record for most internal organs seen onscreen at any one time. It was a well done film, and it deserves such credit.
