As I noted above, this information has been on-line for some three days now, and has gotten very little air time in blogs or any other form. While I find this somewhat astonishing, given Babylon 5 fandom, I have to say that I am of two minds about this subject. On the one hand, maybe this is an indication that the attentions of the fans have shifted elsewhere, and the entire B5 franchise needs as breather. Or maybe this suggests that, to quote paraphrase G'Kar, Babylon 5's time has come and gone.
When it comes right down to it, the fandom associated with Babylon 5 has been very vocal about the series over the years. The last two projects, B5: The Lost Tales and B5: The Legend of the Rangers, were successes for Warner Brothers, but not to the point that they were encouraged enough to go right into some more B5 projects. Add to that the fact that JMS has seemed somewhat discomfited in his own universe of late, and perhaps it is time that Babylon 5 was retired from service once and for all.
The Babylon 5 television series was a science fiction series that bears all the hallmarks of being a classic that will be fondly remembered by science fiction fans in times to come. While I would like to see more stories set in that universe, perhaps it is time to let the last of the Babylon stations rest (although as we all know, it's going to self-destruct eventually).
I can live watching the DVDs of the series and the movies that make up the Babylon 5 legacy. And really, when push comes to shove, what more can the fans want of JMS? It's time to let the old girl go...and if the show does get resurrected in some form down the line, well, I'll be as pleasantly surprised by that news as anyone else. And hope that the show, if revived, gets the respect from the people making it that it deserves.
