* Echoing just about everyone: KORRA AND ASAMI WALK OFF INTO THE SUNSET TOGETHER. EEEEE.
* Pretty excellent epic moments for nearly everyone, especially given the giant cast of characters and limited time.
* I liked that a) Milo had an idea that was genuinely useful, and b) that the mecha suit had window-cleaners, because that was kind of an obvious weak point. And yet the balloon-arsenal slowed it down for a bit, which was all they had really been able to do at that point anyway.
* When did Kuvira get stormtroopers? The whole bender-duel-in-the-suit was very Star Wars.
* Hummingbird mecha suits!
* Mako getting to lightning-bend again! I don't think he'd done that much if at all since way back in the first season and it was an excellent potential heroic sacrifice moment for him.
* I am unfond of Verrick, and want Ju Li to run off with one of the Bae Fong kids or someone, but if he had to have a wedding, they pulled it off entertainingly.
* What was that scene with Pema?? I wouldn't have minded at all if she just rushed around in the background and didn't get screen time, but they wasted a whole scene on her being inappropriately, mostly ineffectively motherly? That people-managing role in a crisis is really important, and Pema could plausibly have been good at it, but no, she's just treating everyone like kindergarteners until the badger moles show up.
* But on the other hand, BADGER MOLES. WITH SINGING. And Wu being surreal and campy and...that actually manages to be incredibly effective.
