David Gerrold's amazing two-part interview covering Roddenberry, Fontana, TOS, TAS & TNG:

At turns fascinating, insightful, heartbreaking, heartwarming, infuriating and even savage, it's certainly the most interesting ST-themed interview I've ever watched / listened to.

For me, it also tied various ST lore and insider info together (thanks, Memory Alpha!), especially DC Fontana's book, which I recall as being pretty scathing when it came to Gene Roddenberry. But after watching this two-parter, I get the sense Gene's lawyer and the network itself had a pretty disastrous, and even cruel influence on the "Great Bird of the Galaxy."

Part two is here:
