The finale was pretty great. It was definitely an emotional rollercoaster, and I love those.
Hiroshi and Asami, oh my gosh. Best story arc in the entire series. Seriously, I loved it so much.
I was kinda surprised there only seemed to be one casualty. Also surprised Milo had an idea. He's been kind of a pill this entire season. Worse than Pascal.
The Spirit Portal has indeed enchanced the value of Republic City's MacGuffen-ness and everyone shall obsess over it forevermore. Woot...
The fight sequences were pretty awesome. Fitting for the finale.
And then there's Korra and Asami. Really mixed feelings about this. I'm glad they were very much hinting that they were dating or at least were going to be dating, but... I can't help but feel like that would have been handled differently if the pairing was heterosexual. You know, like Aang and Katara kising twice, Sokka and Suki kissing, Sokka and Yue kissing, Zuko and Mai kissing, Mako and Korra kissing, Mako and Asami kissing, etc. Or, you know, verbally verifying they had a relationship.
Instead it feels like it's up to speculation, and that people could easily disregard it if they wanted to, which seems odd considering almost every other ship in the series.
I did like that they went that direction, though, that actually makes me really happy. Also, I think it's sweet they were in the same pose as Aang and Katara in Avatar's finale. Also liked that they both ended on the word "perfect"
