I like most star trek variants cept the last season or two of ds9, babylon 5, lexx, FARSCAPE!!!, Red Dwarf..... and:
The Other:
stargate, stargate, stargate, stargate...
and lotsa space anime (Gundam Wing for ex), transformers >.<
Firefly... erm... Crusade, 1st two seasons of andromeda...
WHen i was younger i really liked the half hour sci-fi teen show Space Cases (sings the theme... 'stuck aboard a mystery ship, which soon was sucked through a spacial rip, and now their stuck on a long, long trip,), and Animorphs (there was a short lived tv show on nickelodeon of the book series)
