Lexx is a science fantasy TV series that follows the adventures of a group of mismatched individuals aboard the Lexx, "the most powerful destructive force in the two universes" from which the show takes its name. The Lexx is a living spacecraft that resembles a dragonfly. It is capable of destroying planets with ease, and eats the debris as fuel.
Got partway, don't plan to finish for some reason. Either the quality dropped (The Simpsons), or I really wanted to love them but they just didn't click for me (Buffy), or what I saw was interesting, but not enough to invest time in the whole thing (The Borgias).
