Also, I should add that he supposedly got along with Nimoy and Kelly.
He saw himself, Nimoy (Spock) and Kelly (McCoy) as the three stars and the other four as supporting players.
The other four (Nichols, Takei, Koenig and Doohan) wanted to be elevated to equal status in everyway (storylines, press and salary) with the other three.
I'm not saying Shatner is/was an angel, but a lot of this anti-Shatner/Captain Kirk crap was coming from people gnawing on sour grapes.
