[Caduceus]

I agree with SciFi's Friday night line-up, though the two SG's are fluff. Fluff that I enjoy, but fluff nonetheless. Battlestar Galactica I would stack up against any drama as far as character development and varying sorts of topicality - from abortion to military and civilian governments to church versus state, anyone?

My wife swears by Veronica Mars (the first season, anyway).

Smallville can be good, though a bit campy. With children I have a difficult time seeing it every week.

Speaking of children, you forgot the all-important children's networks:

Noggin (commercial-free toddler TV from 6A - 6P)
Baby First (24 hour "pay" channel)
