The above mentioned, Farscape, and Lexx. Lexx is an awesome underdog. Not to everyone's tastes, but I believe up there with the best orginal sci fi. What you should try and do sometime is watch all the Star Trek series and movies in chronological order. Which is harder than you think seen as The Next Generation, Deep Space 9, Voyager and the later movies all overlap. It can be done though. Ask if you wanna know the order. You basically have to watch some of the seasons concurrently, alternating episodes like they said you had to with series 1 of Angel and whatever season of Buffy was on at the same time. Don't touch either of those shit fests though, not even if you actually like vampires.
