I loved the first Paranormal Activity. I found it be perfectly paced and suspenseful, with a satisfying payoff. The second one wasn't as good, but it had some good jolts and jumps.
The law of diminishing returns applies here. Yes, it still has some good scares, but the pacing isn't as tight, and I found the middle section much more effective than the somewhat anti-climactic ending.
This one's a prequel, going back to the childhood of the two grown sisters who are the subjects of PA 1 & 2. For all the events that happen in this movie, I can only assume their memories were erased.
Katie and Christy have a stepdad who edits wedding videos for a living and set up video cameras around their house when things start going bump in the night. This movie does have several effective stretches where we're glued to the screen, wondering where our eyes should focus. What might jump out?
I suppose the franchise could figure out how to do a PA 4, but at this point, Katie and Christy have been done to death. Don't turn into the Saw franchise.
