You got it wrong, Shatner was the ass, Roddenberry was a lot better. If you want to read the below, replace the stars with the F word. It's about Will Wheaton meeting Shatner.
Oh I'm sure Shatner was the perfect prick, but a guy I work with watched a documentary on Star Trek and they said that Roddenberry would undermine all the writers, actors and every other swinging dick on the congo.
I'm not a typical Trekie. I loved the original with Kirk, Spock, Uhura, Bones, Sulu, Scotty and Checkov, but I never watched any of them after that.
