ya I was pretty disappointed with the fight between Zuko & co. vs Zehir & co., thought it was pretty anti-climatic. Like, I get that they don't want to have a massive boss battle right away in the beginning of the story, but come on, they've (Zuko) supposedly fought them before and won, why couldn't they put up a better fight than they did? Zuko couldn't even beat the earth bender one-on-one smh.
At least Zehir vs Kya was decent, we finally got to see her in action and she seems like she's at least better than Katara was in her prime in the original series which was cool, so we know that Katara only got significantly more badass as time went on.
I like the hero worship of Toph in the metal city, I'm so stoked that she's actually alive. Hopefully we get more than just a couple cameos of her like we did with Katara and get to see her earth/metal bend at a grandmaster level.
