Tonight I watched the latest and final episode of Crusade, "Each Night I Dream of Home", which is about the moral issues involving in investigating the Drakh virus, and has a few old friends from Babylon 5 show up (though not the one I thought when a Warlock-class destroyer appears at the beginning). It's okay, but not outstanding. Seemed to clearly be set-up for later episodes, but was rendered moot by (1) some of the episodes which occurred before these last five, which were actually filed first, and (2) the fact that there won't be any later episodes.
A pity, the series was starting to get good. But, I guess the chances that it will ever be revived are very small. Meanwhile, Straczynski is reportedly working on a new SF TV series, and he's also doing his Rising Stars comic book...
