There is, apparently, no rock bottom for film director M. Night Shyamalan. How bad, exactly, is his latest film, The Last Airbender? Here's Roger Ebert: " The Last Airbender is an agonizing experience in every category I can think of and others still waiting to be invented. The laws of chance suggest that something should have gone right. Not here." He particularly takes issue with the film's retrofitted 3D effects, calling it the "drabbest, darkest, dingiest movie of any sort I've seen in years." Ebert says the film should have been animated as anime, attacks Shyamalan for casting white actors for characters who were Asian in the source material, and calls the performances "are bland, stiff, awkward and unconvincing."
