If the result features around 1,783 too many fart gags, to be fair, it also boasts a couple of genuine minor scares. Although there's no doubt that the film's most horrible sight is a way-too-long shot of Swardson's naked rump.

The film similarly boxes itself in when it feels the need to mimic the third-act occurrences of "Paranormal Activity" when it's obvious that improv had the film going in an entirely less predictable direction, clearly pointing out the fallacy of A Haunted House: you can't parody something and also try to emulate it as well.

For 85 rude and raunchy minutes, he does his best to drive a comical stake through the heart of horror's hottest franchise and the "found footage" genre. He doesn't exactly succeed.

By eliminating the winking, broad strokes of the filmmakers' more successful spoofs, they've made a film that is not only dumb, but dull. It's like watching a snuff film, only it's the audience who's dying inside.
