Yeah me either,as a Doctor Who/Blake's 7 SFX have never really been important to me,it's the stories. Still I know some people can't get past the early CGI. In my case after a while I got used to it and it just became the way things looked in the B5 universe.
Watching B5 for the first time is a great ride,have fun:)
Oh and I just watched the second episode of Chuck again and did anyone else notice that while taking the test he said the flight from Lost was shot down? Now that is a cool Easter Egg.
