There was; Crusade (sucked - took everything B5 fixed from ST and made a series out of the bad stuff), One character, a techno-wizard, they tried to make mysterious. Nearly every episode ended with him leaving on some secret mysterious, mission & stating "expect me, when you see me" then the next episode starts, he's right there, never left ??? [drool] 13 episodes, horrible writing, & bad acting, I think that's what killed the franchise.
Not entirely true, after about the 3rd or 4th episode, TNT started trying to stick their fingers in the writers room. The head writer said in one of the notes from TNT, they really wanted Silk Stalkings in space not a space opera. B5 wasn't sexy enough for TNT so it was canned. I think it was the Pak Mara (sp?) porn episode when the series creator called the entire project "stillborn." It was a shame.
A movie was shopped around a few years ago, that was about David and the Rangers during the psych corp wars. It never went anywhere, after the Lost Tales DVD wasn't that big of a seller. The DVD was good, OK it half good
The ghost story sucked but the future war one was good
Watching Vorchans ripping apart Warlocks was worth the price of the DVD for me!
