Of course The Last Airbender first part is a success (financial), but this is not the end for sure because The Last Airbender 2 movie the second part will be a success.
What is spectacular in The Last Airbender, in short: everything happens in a world in which the elements (water, earth, fire, wind) can be controlled by people known as "benders" (just as Captain Planet controlled the same elements:)) and the Bender - wire them started a war to get his hands on other items.
The only one who can stop this war is a little boy named Aang (Noah Ringer), the last Air Bender, but with much greater powers than those which only allow him to control the wind. Try to help some other kid's with special powers and together try to restore peace on Earth.
The Last Airbender 2 like The Last Airbender first movie seems a very nice fantasy movie with lots of spectacular special effects, with more action scenes and a little blah blah. The launch date for The Last Airbender 2 is not announced yet but could be in 2012. Of couse when the trailer for The Last Airbender 2 will be avaible for sure the trailer will be here.
