I've occasionally wondered would I be such a fan of this episode if it weren't written by my favourite writer; however, it's so much better than any other episode, I've got to assume 'yes'.
Ellison is an excellent fiction writer, but his fiction is eclipsed by his non-fic. "The Glass Teat" is one of the best books on television you'll ever read. In fact, any of his non-fiction is essential reading for anyone with an interest in the sociological effects of television.
