I was absolutely a big fan of Avatar when it first came out. I thought the fight between Aang and Ozai was just gangsta even though it could have been better. I just feel like in most shows when they end it's like really emotional and sad because it's the final episode, but Avatar just feels like it was rushed to me and when it ended it was like..."Ok Avatar is finally over, let's watch Naruto" I don't know, but Avatar to me even though it was funny, it still felt a little emotional at the beginning because it was like the whole world was on Aang's shoulder and he was only 12 and was the last air bender. so it was kinda heart felt, but it didn't feel like that on the last episode.
I think another thing that didn't help the exit of the show was the all of a sudden disappearing of new shows. Nick was showing new episode and then all of a sudden they stop showing Avatar for months and didn't give any hints of it going off air for a while and how long we have to wait until new episodes come. Then out of a Blue Nick advertises Avatar about 2 weeks before showing new episodes and then says it's counting down until the movie. I'm not sad when a show ends, but when a shows end it's like "Awww...it's over", but Avatar was like "Oh...it's over, wish there was more to it" And I hate when shows end with a cliffhanger on the last episode because I wanted see Zuko's Mother.
Well I guess I'm not sad because Naruto's better, plus Bleach still showing new episodes and Heroes' coming back in September a minor set back because of Writer's Strike, but Thank God it didn't get it cancel.
