For a film filled with clunky, declamatory exposition, this turned out to be quite diverting. The kid found parts of it frightening, but wanted to keep watching.
The fellow playing the Fire Bender prince was frankly a bit too high quality for the rest of the action, but the others were pleasant enough to spend some time with. Not so much the water bending princess, who seemed to have popped over from gossip girls and had a more than unusually unfortunate hair style in her first scene. I did like the glowing fish - always a positive.
Another positive, the father in this film is so horrendous that it will make parents look really, really good to their children.
