I personally didn't like this season much at all, but I really did love this finale. The first twenty minutes really blew me away ;)

Except it does. It solidifies Korra's place in animated TV history. The final two seasons are that good. The reason Sava makes the connection between Korra's high quality and this show is because a lot of the people who worked on Korra made this show.

Oh be quiet. Books 3 and 4 of Korra are some of the best animated seasons of TV ever, and totally on par with Avatar.
