A lack of originality does hold the film back, but with decent work behind the camera and a breakneck finale, Paranormal Activity 4 is still a solid watch if you've an evening spare, or horror film night coming up.
Little depth or subtext here. It's tough to care about the fate of a generic, whitebread family and its blonde-in-distress living in an airless, gated-community Nevada. We've seen the creepy kid and freaked-out teens in countless fear-fests before.
The chills are centered at the end of 'Paranormal Activity 4.' Even more creepy is the "cute factor" of little kids that permeates most of the movie. Although the franchise may be running out of steam, this segment is more than mediocre.
The popularity of this reliable if repetitious franchise suggests that anxieties over the ubiquity and invasiveness of social media and its related technologies may trouble even the most enthusiastic members of the plugged-in generation (even teenagers).
Anyone who's seen the other entries can tell you this series has never been about the story. "Paranormal Activity 4' proves this once again, and when you factor in the lazy writing and complete lack of scares, it easily earns the title of worst entry yet.
