When the show premiered, nobody said "wow, that's bad CGI!" They said "WOW! You can do that with computers!?!? That looks GREAT!"
When I watch a TV show I put my head into the time it was made. B5 is an archeological gem of early TV CGI, and I love every minute of it, no matter how much better CGI has gotten over the intervening years. I'll expect current-quality CGI in any NEW B5 productions that may happen, but I'm perfectly happy with the originals as they are.
This. More and more people these days don't have the brainpower or the patience to appreciate older shows and movies because "da speshul effeckts r LAME!11."
Then again these are usually the same idiots who are blown away by shit like Sanctuary so I don't even know what the fuck anymore.
