I have always found trees at night to be things of intense mystery, the way branches claw their way through the darkness. As a kid, I would go into the woods at night and bask in the feeling. I think there is something skeletal about the way trees look at night, and being in the dark woods taps into some primordial part of the brain where fear lurks.
This issue certainly does a great job capturing the imagery of trees at night and tapping into the visceral fear that these images can stir. For me, that is the true brilliance of this comic, although the writing is also very good. But the artwork is truly from another realm. I keep finding myself drawn into the nightmare along with the characters. Definitely gets two thumbs up in the horror department.
