Ugh. It started a bit worse than the original and ended absolutely horrible.

Honestly, I think pro-bending was the only thing holding the series together. It managed to keep the side plot queue (which apparently the writers needed as the main plot seemed to only come around once every few episodes) filled with something halfway decent. The only other idea the writers had was "love triangle tension". I stopped less than halfway through the second-to-last episode, because I didn't like it anymore. The Avatar writers are the worst romance writers ever, it's as if they learned nothing from the first show, and in fact lost the point of "don't make it too heavy/central/whatever, this isn't a romance show".
