I read so many (wrong) posts here criticising a lack of character development in the last two Star Trek movies, and now you three here tell me character growth doesn't matter?
I think, for our production at least, we are generally content to show the same amount and kinds of growth in the characters that we saw them undergo back during the 80 hours of Trek in the 1960s. I'm not exactly sure how much of TOS's popularity was driven by character development. I think that Star Trek, like its sister show Mission: Impossible, was largely plot-driven. But I'm sure Kirk must have grown and developed substantially between "Where No Man Has Gone Before" and "Turnabout Intruder."
I think your suggestions, though, would make for a very interesting approach to Star Trek that many people would like to see. I know *I'd* watch it! I think just about everyone here would be encouraging of your efforts.
