Like horror classics ranging from Cat People (1942) to The Haunting (1963) to The Blair Witch Project (1999), it suggests its terrors rather than explicitly showing them, which leaves far more to the imagination and sends more genuine chills up the spine.
That's even less than “The Blair Witch Project,” the breakout hit from 1999 that “Paranormal Activity” will be most compared to -- for obvious reasons, though “Paranormal” is the scarier of the two.
Comparisons to The Blair Witch Project aren't entirely off base, either, in that Paranormal Activity is about a decade past its sell-by date with a tale of irritating technophilia that would have felt more current in the Y2K Ludditism of 1999 than it did in the resigned technocracy of 2009--explanation in part for why it's already out of the conversation and never stirred much outrage or controversy when it was causing audiences of teens to collectively fake-shudder the way festival audiences collectively fake-cathect.
It has been dubbed a phenomenon and compared to the 1999 low-budget sleeper hit The Blair Witch Project.
Granted, the movie is less inspired or original than The Blair Witch Project in its conjuring of offscreen spaces and forces, potent as these remain in the newer film, and it suffers by moving some of the occult "backstory" that Blair Witch savvily dispatched at the outset into the third quarter of the film, and barely seeming sure of why it's doing this.
Ten years ago, Daniel Meyrick and Eduardo Sanchez become overnight sensations when their no-budget shocker The Blair Witch Project (1999) captured the demise of three doco-makers; both Jaume Balagueró and Paco Plaza’s Spanish-language [REC] (2007) and John Erik Dowdle’s shot-for-shot English-language remake Quarantine (2008) utilised found-footage ‘wobbly-cam’ superbly; Matt Reeves’ big-budget Cloverfield (2008) did not.
