People hated "The Last Airbender" for many reasons. I'm not going to argue any of them, as I've seen it (with Rifftrax) and it was mind-numbingly bad in a way that actually beat my incredibly low expectations. But among the things people say about the film adaption of the beloved franchise – the hate of the actors, the plot, the acting, the direction, the story, the intermittent attacks of slow-mo - there's one thing I rarely hear brought up.
Why a film anyway? I mean let's assume that you have some driving reason to turn "Avatar: The Last Airbender" into some other media form, why a film?
