I cant recommend The Last Airbender as a movie worth shelling out $8 bucks or more to see. It just isn't that great. The movie looks nice- the costumes and the martial arts choreography are up to snuff. But the acting was wooden, it was way too dark of a film, there was no humor, and it was just plain boring.
There wasn't a single belly laugh or a "hell yeah!"moment in the whole movie. Shyamalan was the wrong director for an adaption of a children's anime adventure film.
