Re: Synopsis of JMS's synopsis of the "original arc for B5" **SPOILERS
Regarding themes, we've missed a pretty important one, one which had its origins right back in The Gathering; the ability of one person being able to change the world around them. The most explicit example of this was the showcasing of Sheridan's journey. DS9 tried something similar with Sisko, and whilst I enjoyed Sisko's progression, it wasn't as coherant as that of Sheridan.
Personally, I think it's fair to say that both B5 and Star Trek had themes. Not the same themes, which at the end of the day, is great. There really wasn't much need for them both to tread the same ground.
