Ratlady: Spongebob is one of the only shows I still watch on Nickelodeon,another one being Fairly Oddparents. Nowadays I prefer Spongebob over Fairly Oddparents. I usually watch it anytime it's on. I find the show rather appealing and I can't up but really like the characters, especially Spongebob and Patrick. Personally I consider Spongebob one of the best cartoons left on Nickelodeon. Fairly Oddparents is good. I like how Timmy seems to act like an ordinary kid (for the most part since he has fairies) and is sometimes selfish, but in the end does the right thing and, despite his low IQ, has shown quick wit throughout the series.
On Nicktoons TV there's also Jimmy Neutron and Danny Phantom I also enjoy, but not as often. I can't remember why I originally got interested in Jimmy Neutron (probably his experiments and robotic dog) but Danny Phantom I liked because of the unique story and the action. It still had its funny moments but the show was, in my opinion, more serious than Fairly Oddparents.
Oh! And I forgot another nicktoon, Avatar. I like the story, the characters, the action, the comedy, etc. When I first saw the show, I wasn't sure if I would like it or not. But after I did watch some episodes, I admit I was hooked.
Another show I like, a webshow, is Red VS Blue. The main thing I love about it is the comedy. I also like the characters, distinct from one another, and such. I was introduced to it about a couple years ago and I've been watching it since.
I could name some more shows, but I'll just leave it at this.
