You are one out of more than millions that like it. Not everyone one likes everything.Avatar is a dumb show. Both versions.
I don't watch shows that are aimed at children and teens. Nickelodeon's own release statements says Avatar's target audience is 9-14 and extremely popular with that range. I'm 32 so I don't really care too much for current cartoons, but I do admit that I still love watching the cartoons I grew up watching and am watching Power Rangers on netflix because I was a teen when they aired them.
