Remastering, or Remaking?

I noticed something strange while watching a Star Trek (the real, original one) rerun a few weeks ago: the special effects seemed much more modern.

Well, it turns out they're upgrading the special effects as they remaster and re-release the old episodes.

Aesthetics aside (the CGI stuff they're adding is much darker and grayer than the colorful, downright 1960s palette of the rest of the show), I just have a queasy feeling about the enterprise.... Wuggedy special effects are, for me, one of the charms of the original series (as with Doctor Who).
