Please don't take any offense with my opinion but I personally don't love this movie. I watched the series of Avatar: The Last Airbender from which this movie is based off of before watching the movie, and I just want to point out a few things.
First off, Aang's name isn't said as 'ahng' it's said as 'ay-ng'. Plus Sokka's name isn't said as 'soak-a' it's said as 'sock-a'. Second, the arm, hand, and leg movement for little and bad CGI bending isn't very much of a "fun and entertaining movie".
As I said before this is my opinion and not anyone else's. One more thing, why does Aang have symbols on his head, arms, and legs instead of a normal blue arrow tattoo? And where's the laughter? Everything is so serious and not like how it should be. I wasn't expecting any of what happened in the movie. Also why are the Fire Nation Indian when it's supposed to be based in Asia?
