It's my favorite sf series. It offers a unique and zany take on the space opera that nothing else even comes close to. Better, it manages to pull it off. It would be much improved if the series had been given a full fifth season rather than an eventual miniseries to wrap things up, but the conclusion is perfectly satisfying when it comes to the primary characters.
What I've read of the recent comics have been fun, too, although I'm rather behind on them.
