Most Scifi fans I have ran into can pretty quickly rank the four stars –BattleSTAR Galactica, STAR Trek, STARgate, and STAR wars, but what lesser-known or less-prestigious shows hold a special place in your heart?
In the spirit of the question (not picking the most common ones), I'd say Sanctuary was good. I think it was very (very...) low budget (everything is green screen) but the stories were great. There are a lot of fantasy elements but I think it's very scifi.
