It was actually on TNT. Except in my house, because we Didn't Watch Television and the set was in the basement. So in my house all tv shows came on VHS from my aunt. It was seriously good science fiction (with delicately-filmed, so-very-90s canon slash, even) but a lot of people thought it was really depressing. The current equivalent is probably Battlestar Galactica.

Man, SGA is actually the one show my siblings want very little to do with. My brother has seen every episode of SG-1, but apparently space vampires are just too much for him. Too much AWESOME, that is.
