Is 'The Last Airbender,' director M. Night Shyamalan's live-action version of the Nickelodeon cartoon 'Avatar: The Last Airbender,' the "worst movie epic ever"? Time magazine certainly thinks so and it isn't alone -- the film carries an especially rotten rating on movie review website Rotten Tomatoes, earning a paltry 9 percent fresh rating from the nation's top film critics.

This marks the latest misfire from the once lauded director of hits like 'The Sixth Sense,' 'Signs' and 'Unbreakable.'
