ScreenRant - Paranormal Activity 3 doesn’t reinvent the series’ wheel but it definitely refines an already effective format (and ups the ante by adding a few spikes to the rubber). While it’s still unclear where the franchise will go from this point forward, for the time being, the third film will no doubt deliver on (and possibly exceed) expectations. Non-fans of the series won’t find any marked changes to rekindle their interest but anyone who enjoyed either Paranormal Activity or Paranormal Activity 2 will probably consider this film to be scarier, funnier, and ultimately more entertaining than its predecessors.
