The relationship between Kirk, Spock, and McCoy...that is the reason that Star Trek worked as far as I'm concerned. Recent attempts to duplicate that relationship have failed to live up to the original, IMO.

As far as "updating" the FX with CGI...what would be the "point". I like the original FX. I wouldn't mind if the "bleedthrough" (stars showing through spaceships) and the "matte outlines" were cleaned up a bit. But other than those particulars, I really see no need to "fix" something that isn't broken.
