Crusade was the biggest production cock-up ever, with TNT demanding that JMS (the writer) change one of the cast into an 'alien sexual exploprer who gets to know other species by habign secx woith them' just to spice things up a bit.
JMS has an ego the size of Jupiter and he and TNT never got on, until the plug got pulled. JMS wrote two deliberately crap scripts just to (rude thing) 'em, as he himself put it, and the whole mess got pulled.
13 episodes, some ok, a few REALLY bad, and now forgotten,
