Don't 4get Inuyasha (wait I think its done now, i??don't really know, i??stopped watching years ago) and the DBZ series (yep still 2 lazy 2 spell??out the whole thing).??Though the movies were pretty good. ...Pysche.

Its not that, its just that the creators originally planned it 4 just 3 seasons. Being an anime-influenced show, Avatar noteably has some of the qualites of a true anime, and 1 of those is storyline. Unlike most episodic American cartoons (which basically go on an on doing the exact same thing in each episode until people get bored of it and the show gets cancelled... er, "chooses" to end the show) most anime contain storylines and a main reappearing plot devices??(finding a special item coughphilosophersstonecough, achieving the title of something; like a pokemon master or a pirate or whatever, God those shows suck , or defeat the??major reappearing villain once and 4 all; Naroko??or whatever his name was,??etc) which if??overcome,??will cause the show to??end.??The time it takes to accomplish this varies and usually depends on the show itself, sometimes this can take over 180 episodes, other times 7. Most anime last no more than 3 seasons, and the 1s that go past this point seem 2 go on 4ever (it could also depend on if the show is based on a running manga or something.. but let's get into that). The main point is that its what unfortunately makes the show to end, that's were we have some problems. For Avatar, the plot device is obviously defeating Ozai and ending the war. When an show decides to continue on even after completing the main plot device, there can be serious repercussions.??Like an ??episodic??cartoon, the show will have to find a new plot device altogether for almost every other episode to fill in the huge gap left by the one that had been there previously 4 numerous episodes or seasons. The episodes themselves won't be as connected as they used to be, giving the show a "filler" feel. Of course not all shows fall??victim 2 this (not??right away anyway:roll and thye can instead become bigger and better than what they were b4 due to the change (i miss DBZ, the good kind). Above all, the main point of all this is that the creators of Avatar had it all laid out b4 the show??even started. Yeah sure they??had 2 wait 4??the following 2 seasons to be green-lighted by the network but??that's about it. They weren't??really waiting from the start 2 see if they could??go past the big 3 even if they would enjoy it. Only now after realizing how much people have come to like the show so quickly have they began 2 "consider" some additions to the original template. ....Yeah its a still no. ??
