Crusade: The Complete Series (1999)
13 episodes, approx 44 mins each
The first failed spin-off from Babylon 5. In the year 2267 an alien race known as the Drakh, one-time servants of the Shadows, release a plague upon the planet Earth in a final defiant act of douche vengeance. Consequently, all life on the homeworld will terminate in approximately five years if a cure isn't found and successfully administered in time.
Earth Gov orders the destroyer ship Excalibur to scour the galaxy, dig beneath alien rocks and generally make themselves a pain in the butt of everyone else in order to find the magic cure.
The series managed thirteen episodes before being canned. In truth, it wasn't due to the poor quality of the series, it was the TNT network being interfering bints. Listen to the episode commentaries and you'll discover that J. Michael Straczynski had big plans for years 2-5: leftover Shadow tech; government cover-ups; the return of everyone's favourite bad guy behind a badge, Alfred Bester; a magical sword; and something called an Apocalypse Box, which you'll understand if you watch the show. Things could've turned out good.
