The movie itself ... dark and fucked up. (Oh, and was preceded by the ironically titled short Film Makes Us Happy.)
The man-in-drag shrink bothered me; I wasn't sure what the point of it (er, and as soon as I typed "it" I flashed to the girls' mockery of Tracey) being clearly a man in drag.
I thought of Equus when the horse showed up during the sex scene.
Losing your virginity to this dark and mysterious man ... leads to him turning evil and bringing about the apocalypse, versus leads to your little brother dying ... compare and contrast. (Rhetorical.)
When the crows flew up around her I thought that's how the film was gonna end since we now understood the "real" linear narrative (more or less). When she walked by Billy Zero head held high and the water in the background I thought she was gonna walk into the water, a la ancient epic suicides. When the snow started to fall I realized it was the same sort of thing ('cause if she keeps walking in the snow, especially wearing what little she is she's gonna die).
