Re: Is Spock the main character of TOS?
Kirk was meant to be the main character of TOS. But Spock was the breakout star, proving hugely popular with viewers (especially female viewers) and getting more fan mail than the rest of the cast combined. So the network kept pushing for more Spock, wanting to elevate him to the main character. If Roddenberry hadn't resisted that pressure, Spock might've ended up following a similar route to Dr. Smith in Lost in Space or Fonzie in Happy Days, completely dominating the show to the expense of its nominal leads. But Roddenberry and Shatner both strove to keep Kirk central as he was intended to be. At Isaac Asimov's suggestion, Roddenberry played up the friendship and partnership between Kirk and Spock, making them inseparable and equal. McCoy was also able to stay central due to his friendly rivalry with Spock.
So it isn't really right to say "Spock was the main character" as if that were the intention all along. He was the breakout character.
Solid points--especially the references to Dr. Smith (and Will Robinson to a degree) and Fonzie's "takeover" of their series.
