1. The Looney Tunes Show: This is a nice update on the old Looney Tunes. It is sort of like the Looney Tunes meet Seinfeld. It works surprisingly well.
2. Adventure Time: This show has been constantly good with great humor.
3. The Amazing World of Gumball: One of the best new shows of 2011.
4. American Dad: This is easily Seth Macfarlane's most consistently good and funniest show. It has likable characters unlike Family Guy's main cast.
5. Regular Show: Probably Cartoon Network's most adult humor show, aside from the Adult Swim stuff.
Looking forward to Green Lantern The Animated Series in 2012. Bruce Timm has never failed me yet in making good DC Comics cartoons.
