Here's what Criterion has to say:

"The montage of Dog Star Man (1961–64), which juxtaposes its characters, principally Brakhage himself, with imagery of blood vessels and the sun, the forest and the stars, family and architecture, and explicitly erotic imagery, evokes numerous associations, from the banal to the sublime. Layers of faces and rocks and paint on film combine in multiple superimpositions, ultimately building to a meditation on one man’s place in the cosmos that can also be read, apart from its hint of a plot, as a light-poem."

If I was back in grad school, I can see how there's a thousand ambiguities you can write a paper about in this long, silent collection of images. As a human being, though, I don't see how someone can watch this and not be bored.
