Paranormal Activity: The Ghost Dimension

Not the worst of the franchise (I leave that to 4), but since it seems totally different from the others that isn't a good qualification.

"Was it entertaining?" The entertainment factor for a horror movie is how scary it is. The special effects ruined this. It makes up for it by adding action. Characters are actually interacting with the entity. 1.5 out of 3.

"Was it memorable?" The effects were not too cheap. My yelling at the screen for the characters to turn on some lights will stay with me for a bit. 1 out of 3.

"Was it interesting?" The mechanics of the supernatural happenings made me think. The adults caught on faster than their predecessors, but made much the same mistakes. 1.5 out of 3.

Start with 1. 1+1.5+1+1.5=5 An average supernatural movie. While I won't go out of my way to see it again, I don't consider the time spent a waste. Though I don't see the franchise going very farther.
