Scifi and the ocassional intelligent drama.
I'm pro: Stargate SG-1, Stargate Atlantis, Battlestar Galactica, 4400, Smallville, Supernatural, with a little Veronica Mars on the side as my only quasi-intelligent show.
I'm anti: Daytime soaps, talk shows, Reality tv, Dawson's Creek/OC/One Tree Hill, soapy type dramas, etc.
I'm borderline Invasion, I think it leans too much intot he drama side but it is still decent enough to cause indept thinking: see below.
I will complain heavily when something stupid/mundane succeeds over
scifi (if 7th Heaven makes it to the CW while Global Conspiracy never got a chance and Threshold died it's horrid death there WILL be a rant)
I feel that tv should make you think and ponder. Not just the plot but the underlying aspects that some scifi can arise like the state of humanity and the state of man's "superiority" complex.
