OK, there are a couple things which come to mind after reading Jake's post. The first is: Heck yeah! A new season of Avatar would have me so pumped, even if I have to wait a year or so for it to come out! There were several things which could have been covered in a new season: Zuko's mother, resolving the issue with Toph's parents (you know, Hawky never did come back...he probably got eaten by a giant shark-vulture or something...), FINDING SOME AIR NOMADS, the possibilities are limitless in that world. For those of you who haven't read the thread, I would suggest reading a thread about the Dark Avatar made by Gantros a while back. The parallels he drew between his theories and the show were amazing and, though it would have to be re-worked now that the show has been completed, it could totally work. It is definitely worth checking out.
The second thing I thought was that there would be a problem with the new season of Avatar. I know that there are a few of you who would scoff that I'm not a true Avatard, but believe me, I am. The problem is that Bryke planned for Sozin's Comet to be the end, and have ever since the beginning. The concluding scene (Kataang all the way!) was complete and was meant to be that way, if a new season were to crop up, there would have to be scenes where Katara and Aang share intimate moments and that was one thing that the show never truly focused on, and they were able to do this very well as none of the Gaang were in relationships, and so the romance was kept relatively low-key. Also, unless they come up with a stellar new villain (*cough*Dark Avatar*cough*), the fourth season just simply wouldn't be as interesting. Koh, Long Feng, Dai Li agents, etc. would only be good for one or two episodes at best. The good thing about the previous three seasons was that the Fire Nation was always there as a driving force, even when seperate villains from the Earth Kingdom presented themselves in season 2. My final unfortunate point is that Bryke actually did the right thing ending it while it was at its best. Seriously, would any true Avatard want the series to end on a bad season? I think not. The truth is, look at how you reacted to the possibility of a fourth season. Would you react the same way to the possibility of a fifth season? A sixth? I think the answer would be yes. Avatar ended on the best note that it could: sending it further would be an injustice to the show we all loved so much. The ending of Avatar simply reflected the aspects of real life: sometimes not all the questions get answered, but you need to move on. Hopefully, a new show will crop up in the next few years that will replace the hole left by the ending of Avatar. Don't get me wrong, I will whole-heartedly support a new season of Avatar, but not with the zest that a lot of you guys are for these reasons.
