Delany is probably my favorite writer — I've gotten lost in his books many times and they are like trips, with all the possible meanings of that word intact — and he's one of my cultural heroes. Ambisexual, black, polymorphously perverse sci-fi writer. A professor who never went to university. But this documentary isn't even a smidgen as rewarding as his autobiography, The Motion of Light in Water, or Times Square Red, Times Square Blue, which besides being a sexy memoir and an important essay about urban sociology, is also one of the best books about New York City in general, and a reasoned and entertaining argument against Giuliani-ism. I'm not even sure this film would encourage someone not familiar with him to read his books, since they're not discussed much, which makes it a failure in the worst way.
