I am not really fond of even the most "harmless" change to Star Wars effects ... say, for example, the Sandcrawler shots which most people find to be improvements. I do not. I don't like the artificiality of them. CGI looks different than models ... perfect "artist's rendering" skies look different than real skies. Even though these replacement shots do nothing to destroy the integrity of the movie, I do not care for them.
Star Trek might be a different story, though, and I'm willing to wait and see. Having the originals available is always a plus ... and perhaps these will be genuine improvements. Having said that - - the art direction of the show reeks of the 60's (not necessarily in a bad way) ... and I'm not sure improved effects won't look entirely out-of-place.
