Im not surprised Avatar got #1, well deserved for an amazingly done show. I got to say when this first aired i was very skeptical, dint think Nickelodeon could pull something like this off, but it did, and it did it gloriously. The way it built and explored its world was magnificent (the different cultures that were shown were great too), something rarely seen in cartoons these days, a true adventure show. Characters, story, action, drama, comedy, it was all amazing. My favorite character was Zuko, who IMO owned this show, the way he developed through the series is the best thing about this show i think (he definitely grew the most as a person), i loved watching it. Only disapointement was the final battle with the fire Lord, IMO Aang won far too easily, but otherwise it was great.
Not sure i agree on a lot of other choices though, if it was up to me As Told by Ginger, Invader Zim and Danny Phantom would be in the top 5. I consider those three the best on Nick after Avatar.
IMO As Told by Ginger at least deserves an honorable mention, what gives?
