The Legend of Korra

 BAMF Lin Beifong strikes again

F'uck yeah Lin.

I'm kind of surprised to see that they don't always have the foot portion open. Tracking movement and tunnels like that was one of the best advantages Toph had. I don't get why they would purposely take that away from themselves. I would think one of the first training exercises of a Metal-bending police officer would be to train your feet to be able to take harsh environments to take advantage of that ability.

The reason why they can't bend platinum is because it's pure platinum? It's still metal... Kinda like the mecha suits. They're like steampunk gundams xD

If you watch the end of the Second Season of the original series, you see that Toph learns how to metal bend by detecting the small remaining fragments of earth within the metal, and bending that. If the metal is pure, it has no earth fragments remaining, and therefore unbendable ("You can't bend that girder, it's unbendable!").

 Spoiler

Looks like Lin is going to be a bigger part of the main cast now, which is nice, since she's quitting the police to do things "outside the law".

It was also nice to see Tenzin fight finally. Too bad he got his ass handed to him along with everyone else.

Honestly at this point I'm surprised the Avatar State hasn't reared it's head yet. Korra keeps getting her ass handed to her, but I guess her lack of spirituality is hurting her ability to spontaneously activate it like Aang did.
