Paranormal Activity 3 is very scary. There are terrifying jump scares in the film than the other films including Julie (Katie's and Kristi's mother), wearing a mask, suddenly startles the men in the cabinet.

There are also activities that never happen in the first two:

• a ghost is shown with a cloth and staring the babysitter. It suddenly vanished when the babysitter turn around.

• the ghost is seen in a dark figure and moves very quick.

• the ghost kills Dennis by breaking his back (because the ghost never kills the characters without any possessed bodies are used) But it never shows how it began. I will expect it will show in Paranormal Activity 4.

I have seen the first two; this is a prequel to the events in those movies. After watching it, I read the reviews and then watched the trailer. Other reviewers had mentioned scenes in the trailer that weren't in the movie as it was released. I was astonished to see some of the scariest - as well as essential to the story - scenes in the trailer, but not in the film itself. What the heck?!?!? This movie would have been so much better if they'd left those scenes where they fit in the sequence of events. These PA movies are boring for about 3/4 of the screen time; there are lots of segments of the "found footage" where nothing at all happens. Nothing. If they'd left in the scenes that were in the trailer, at least there'd have been more scary moments to make up for all the dull ones.

Paranormal Activity 3 is one of the scariest horror films I've ever experienced. The film tells the start of how everything happened and how it all led to 2007's Paranormal Activity. The film has so much information pouring out that I love it,what I mean,there's so much information like that the demons name to kids is actually Toby. This film is from the director of Catfish the film and the show which I actually hate,BUT considering the amazing directors made this,I might give it a go! Paranormal Activity 3 is a awesome horror film!!!!
