Wouldn’t go to Rolling Stoners for any reason, but here are my favorites.
BSG
DS9
TNG
Sliders (1st season only)
Dr. Who (2005-2006)
Earth: Final Conflict
Alien Nation
X-Files
SeaQuest (first couple of seasons)
Humans (one season in and this is already a classic)
Earth Final Conflict was good until they brought in the vampire energy alien progenitors of the Taelons.
