Okay. I know that the first post says that you can't say that you don't like Avatar, but I really think that just because you don't agree with someone hating it doesn't mean that they have no right posting their opinion.
And now for why I came here: my opinion. Yes, Avatar is interesting, but it definately isn't my favourite. And I do have to say that it's not a Japanese animation, but it is anime, since anime means animation. At first I thought that Avatar was great: it was interesting, the elements were involved, and the characters seemed very intriguing.... However, the over-used expressions that are always attatched to Japanese-style animation sort of became exaggerated and slightly annoying. Another problem is the stereotyping of the element of fire: after a while, the fact that everyone think that fire is evil gets annoying. It would've been a bit more interesting if the element of water or air was portrayed as the "evil" one. Also, sometimes the episodes seemed sort of... Idiotic, for lack of a better word. But please don't think I'm flaming Avatar or anything: I'm just stating my opinion. Despite these problems, it isn't all that bad: the storyline makes sense, the characters are compelling and sometimes even humorous.
Basically, Avatar is okay to me. It's not the best, but it's not the worst, either. It's good enough to watch, but not good enough to obsess over. However, this is only my opinion, so please don't think I'm insulting you or the show.
