I expected Amon taking Korra's bending away, but at least 3 times, for water, earth and fire, but he did it all at one, okay
.
I really did like how she manages to air bend once she was driven into a corner and had no other elements to rely on, it follows the principle of air bending pretty well (consider all possibilities and then choosing the optimal one).
Mako is a waste of space, he dumps Korra for Azami, then dumps her for Korra. If only Korra rejected him in the last episode, the ending would rise by one star.
