Fantastic Fest really, really dug it. In fact it won the award for best doc. So you might want to take my level of enthusiasm with a grain of salt. It will be making a stop in Seattle along with the director in October at the Grand Illusion theater.
If you get the Chiller network it's worth taking a look. But the film lacked the deeper engagement that for me would recommend it as must see theater viewing. Unless of course you're at Fantastic Fest Fantastic Fest where the subject being present (and setting up a haunted house) will add so much to the experience that you sort of have to check it out.
The picture follows three main subjects. The core one is an IT professional whose encompassing hobby is building elaborate "haunts" in his backyard each year for Halloween. He's a meticulous craftsman whose focus is in the details even though he knows most visitors likely will overlook such care. His family appreciate the focus to differing degrees but are mostly sympathetic. Heck, it could be worse what with an obsession like traveling to film festivals or something. He's the way the filmmaker's drive home their "follow your passion" point of the picture.
The other subjects include a city worker who goes more for volume than quality and a father/son team who come off as unusual in more ways than the hauntings.
By the end I knew more about the haunters subculture than when I started and definitely cared about the film's main subject, to the extent of worrying about his choices. Overall even at 81 minutes it felt a tad long. In summary not the best film you'll see all year. But will definitely make you wonder about if there are guys in your neighborhood doing the same. And perhaps about their clearly unaddressed liability issues for such haunts.
