He got it exactly right. Me and my friends had a 4~5 hour discussion about how bad it was and decided to have a marathon of the cartoon to wash away the filth that the movie spewed.
For example, an Earthbender can take rocks around him and bend them to whatever shape he wants. He is limited to the earth, though, which for some reason (even in the cartoon) excludes metal except for those earthbenders who are strong enough. So in the cartoon, the fire nation imprisons earthbenders on a metal ship so that they can't earthbend and escape. M. Night Shyalaman, however, imprisons the earthbenders in A STONE QUARRY and somehow it has the same effect as a metal ship. I almost walked out at this point.
