Oh and as for airbender, I think this review pretty much covered it
"The movie was fair. Big sigh. Where do I start? Well let's start at the sticking point that everyone has had with this movie. In case you missed it, a lot of noise has been made because Noah Ringer (Aang), Nicola Petlz (Katara) and Jackson Rathbone (Sokka) are White actors cast in the roles of Inuit and Asian characters. While I didn't like the fact that they white washed 3 of the main characters it was not that much of a distraction, especially once they left the Southern Water Nation. The biggest problem with these actors is that they sucked. Their acting was the equivalent of kids reading bad book reports to a captive audience. While there may have been better actors of color out there, in their defense, it wasn't totally their fault. M. Night Shyamalan wrote, produced and directed it, so he's responsible.
However, considering that he took roughly 420 minutes worth of material and condensed it into 94 minutes gives him very little time to briefly touch on very complicated and sophisticated material. Granted it was great material, but he only had 94 minutes to present it. "
"The fun, happy go lucky Aang was turned into a sour, drab 12 year old. Sokka's joking, ingenuity and protectiveness was turned into weird looks in close up with little meaning. The preachy, motherly Katara was just there, not really serving a purpose. Zuko, desperate to regain his honor so that he can return home as heir to the throne was somewhat empty. Side note - actor Dev Patel is definitely an actor to watch. He took lousy material and made it look good. Also for the fans of the Kyoshi Warriors and Suki, they were totally cut. Uncle Iroh was very caring but he came off as a whiny woman and when we did get to see the dragon it was an empty scene. And finally while Commander Zhao came off as having testicals the size of watermelons his character also came off as totally confused and unsure
The sad truth is, it is completely impossible to present such complicated and sophisticated material in 94 minutes. If I hadn't been a fan of the series I would have thought it was the worst movie of the year. Only fans of the series can follow what is going on in the movie and we were left wanting. I understand why the reviews were as bad as they have been.. "
according to my little cousin (fan of the show) this reviewer described how he felt about the whole thing
