I haven't really watched Disney Channel that much, although I have watched Phineas and Ferb a few times. It was allright, but everything else is just retarded live action "comedies" (and they're probably not even funny) as far as I can tell.
Nickelodeon. Oh, Nickelodeon. Jimmy Neutron, Fairly OddParents, Spongebob, those were the classics. Now all that's ever on is reruns of SpongeBob (which has sucked and been since 2007, by the way), ICarly, and Victorious (which are stupid "comedies"). Back in the day, I could tolerate Drake and Josh, because it was actually sort of comedic.
Cartoon Network. They had the best shows ever. Duck Dodgers, Samurai Jack, Looney Tunes, Tom and Jerry, Foster's Home For Imaginary Friends. Just, great material. First part of Cartoon Network's 3-year 'crap lineup' came Chowder and Flapjack. Chowder was just a stupid screamer cartoon spewing nonsense bilge. You know the type. Now, Flapjack. It was just too strange and annoying. The barber guy was a weird pervert-serial killer, and the way the kid kept yelling 'adventure'. Just strange. Then they started in with "CN REAL". Any of you remember that? That stupid ghost show (cancelled), Dude What Would Happen (also cancelled), and Destroy Build Destroy (still on somehow), which were all fake and stupid. Around the same time they launched Total Drama Island, which was sort of funny the first season because it made fun of EVERY reality\island show. But then it got stupid, and was cancelled. Good job CN. A lot of their new cartoons are really funny. Regular Show-LOVE IT. Especially the unicorn bro episode. Now, Adventure Time. I'm sort of impartial to it. It's funny in some parts, but is very, very strange. Although Pendleton Ward SAID he didn't use drugs while creating the show, I doubt it. The Adventures of Gumball, I haven't watched much, but from what I've seen, it's a bad show. Not that the material is badly written, it's just NOT FUNNY. Now, this Problem Solvers show. Just a screamer. It'll be canceled in a year. I've never seen Secret Mountain Fort Awesome, but from the name I can tell it's another nonsense screamer.
That pretty much sums it up. Cartoon Network is in the lead with older kids, but Nick and Disney will always have it's following of 10 year old girls. Real, quality cartoons are slowly fading away, and I've given my opinion.
