Yay for being half right, Asami not evil, but daddy turned out to be. Oh well, at least the mechs were really neat, Big Daddy from Bioshock was pretty much my first reaction when seeing them.
I still agree it's kinda pathetic how the benders keep losing essentially, especially when we're talking about 3 masters and earthbenders being able to bend metal (which itself can't be too easy given Toph had to discover it, and likely not everyone can sense the impurities in metal that easily). I was also annoyed how they still used little metal wire bending against giant mechs, seriously just crush the fuckers with good ol fashion earth bending, yeesh...you're in the enemy lair, who cares what flooring you might destroy. And how is it that platinum can't be bent either, that kinda got lost on me...and who cares where Asami learned to fight? May as well ask why she's able to drive a racecar expertly (even though she did explain), she's a rich girl and probably has had plenty of time to pick up plenty of moves.
I will agree though, Pabu is pure awesomeness. And Bolin is growing on me as well despite initially not caring for him (while conversely I'm caring less about Mako now).
