Boring with some effective moments. A short film stretched to feature length.

Rating: 3/10 (29 December 2009)

"Paranormal Activity" reminds me of too many Saturday Night Live skits that were made into movies. Great ideas stretched to make 90 minutes. The first 30 minutes or so (and it's only 86 minutes long) are very boring. It drags. There are some really good and effective moments that can send a chill down your spine, but they are separated by scenes that seem to be pure filler to make this a movie and not a short film.
Also Micah is obnoxious! Yes, he's insensitive to Katie's concerns and just a huge jerk. Whether he was written that way or the fault falls on the director's shoulders, since Oren Peli did both, it's his fault. For me, Micah's obnoxiousness was a distraction.
SEMI SPOILER ALERT (No details but hinting at how the movie ends) Finally, there was no payoff in the ending. A real letdown. I have to wonder if Peli watched "The Entity" before writing this script. Same concept but a much better film.
