As the movie nears the end of its short course (at just eighty minutes and change, it’s like a jury-rigged surface-to-surface missile loaded with dynamite), the video actually disappears for long stretches, just as rationality disappears from the mind of a man or a woman losing his/her grip on the real world.
The footage becomes increasingly jerky, the cuts weirder, the conversations increasingly disconnected from reality.
Blair Witch, it seems to me, is about madness – because what is that, really, except getting lost in the woods that exist even inside the sanest heads?
