All of mine have been covered here. Everyone seems to like the same stuff....
EXCEPT Lexx. I don't think that has been mentioned yet. Lexx is so far out of here (so much more than Farscape) that it's hard not to watch (it pushes the boundaries on almost everything...) It's witty (in a stupid way), but adventurous as well. A good mix for a little fun.
And then there's Knight Rider. I'm a fan of 80's shows, and Knight Rider is up there. When I was younger, I always wanted a black Trans Am with a red sensor bar up front (and entirely bulletproof, of course. And don't forget the turbo boost. It's a must.)
