I decided to review this film as if it was not a knock off of Paranormal Activity. The title and the execution invites comparison, but what are the film's own merits?
The set up in Paranormal Entity is quite interesting: Having lost her husband, a woman seeks contact with him through automatic writing. Something from the beyond reaches out to her, but it becomes increasingly clear that is it not her dead husband. And soon the entity starts showing an unhealthy interest in her nubile, young daughter. What is it and how can they stop it?
In the hands of a skilled film-maker, this plot could have had the makings of a blockbuster. Instead the device used is "found footage", which is very much hit or miss. If it's done well and is believable there is very little chance of screwing it up. If it's done badly, it is vaguely embarrassing to watch, like failed attempts at viral videos. Paranormal Entity is not too bad, although, occasionally over-acted.
The pacing is more of a problem. It starts out fairly decently, with the creepiness being turned up slowly. But about halfway through, the creepiness is dialled up to 10 and left there for the remainder of the film, completely desensitising the viewer. By the end of the film, I found that I just didn't care any more.
Another problem is the inactivity of the family. Beyond calling and calling a parapsychologist that inconveniently has gone on holiday, they don't actually do anything to solve the problem, which means that it's difficult to root for them.
This film should have been thrilling, but it isn't. The concept is good, but the execution just doesn't live up to it.
