I enjoyed it, though I think the desert was the most three-dimensional character in it. Still, a good meditation upon a setting is a nice palate-cleanser every now and then. I think the coyote angle was hit a teensy bit too hard; those notes threatened to overwhelm the melody now and then. Still, one can be forgiven for over-emphasizing that a little, given how appalling some of the actual facts are.
I must say, I was waiting for some sort of Final Revelation about the narrator, but if there was one, I missed it. Was it just me that had that sense of building expectation?
