Star Trek: Voyager
I'm not a Star Trek fan when it comes to TV, but Voyager is the one huge exception. I love this series, even to this very day. I collected them all on VHS, and still own them for posterity, now I have them all on DVD too. Obviously, some episodes are pretty bad, like with any series, but overall it's great. Enjoyable characters, villains and situations. And The Voyager herself rocks!
