Harlan Ellison was a brilliant writer, but the number one rule of writing for someone else is that you have to expect it to be rewritten. That he could not comprehend that when that is the industry practice, especially for television, has always baffled me. His vemon at Roddenberry and Star Trek because of that was undeserved. Television shows wanted talent and great scripts, but even the best writer did not always understand the series and what the audience was expecting so the producers and staff writers would massage all the scripts to fit with the show. We see that in TOS seasons 1 & 2 which are pretty even and maintain a high quality. With season 3 we see what happens when they don't do that. The season was up and down and some stories are way off. Harlan was always entertaining, but some of the things he chose to get on a high horse about were absurd and made him look bad. How he did it was entertaining, but not very professional.
