Man, I can't believe I didn't see this thread before.
Modern faves:
The Adventures of Merlin (so looking forward to Season 4's premiere tomorrow! And Colin Morgan's coming to Supanova Brisbane in a couple weeks, yay!)
Big Bang Theory
Mythbusters
Futurama
The Simpsons (I agree, they're not as good as they use to be)
Classics that are not made anymore:
Sabrina the Teenage Witch
Xena Warrior Princess
Hercules: The Legendary Journeys
Young Indiana Jones Chronicles
That 70s Show (up to the point that Topher Grace leaves. Turned to tripe at that point).
Darkwing Duck
Ducktales
Talespin
Star Gate SG1
Just Shoot Me!
Guilty pleasures (if the lists above ain't guilty enough already):
Batman (the 60s series... its just so camp!)
The Green Hornet (yeah the 60s series with Bruce Lee, better known in Asia as "The Kato Show")
Any Looney Tune related TV show
Batman the Animated series and the Batman: Brave and the Bold.
Yeah, so my TV diet is mostly made up of animation, sitcoms and sci-fi/fantasy/adventure shows. I'm not really into the crime, drama and medical shows.
