Var William Shatner verkligen en ryck på 60-, 70- och 80-talen?

Detta svar listar flera utdrag från artiklar som teoretiserar varför Shatner inte kom fram under NASA: s avslöjande shuttle Enterprise. Halva av dem är mindre än positiva och låter som Bill var en känd ryck då. Jag har bara hört bra saker om honom och är inte säker på varför allt som hatar blev kastat runt.

Här är de aktuella utdragena (betonar min):

But where's is Shatner? He probably didn't attend, because he's too cool for school. Or maybe he was banging a NASA girl in the shuttle bay, who knows. But all is forgiven: At least he went back to NASA to record the last wake up call for Discovery.

If you don’t recognize them, that’s the cast of the original Star Trek television series, minus William Shatner who was apparently too important to show up. (Actually, I don’t know why Shatner wasn’t there, but it’s no secret that he frequently behaved like a colossal jerk during the ’70s and ’80s.)

Therin of Andor: Shatner made a habit of being absent from such high profile events, probably his agent holding out for an appearance fee. He was also absent from all the other actors' Hollywood Star Ceremonies (except Nimoy's and Roddenberry's), and more recently George Takei's wedding.
WHF: He was probably the only one with a job at the time and had to work.

Så var William Shatner så illa som de säger att han var?
