This show is just not smart enough to make meaningful political statements. Just in this episode we go from Jefferson witnessing torture to "I have an irrational fear of zombies and don't know the difference between a cure and a vaccine"

No… He was a villain to challenge the Teen Titans but in truth his methodology and skills are easily a challenge to Batman and in a universe which isn't likely to bring in the Teen Titans any time soon, Batman is without doubt the best challenge for Deathstroke. And Ra's al Ghul notwithstanding not a lot of Batman's…

Why didn't Smokey show off the fan? It's their most impressive move!

I've seen comments before saying that Bismuth was right, and whilst it's certainly not a black and white situation, I'll add my own bit. Since the homeworld gems outnumber them like they do, it's possible, even likely that if they use that weapon, a homeworld gem would either steal or worse replicate it, if they did…

After Azula went crazy (well, crazier) and lost her edge, I get a strange feeling that's coming for Kuvira too

Do you remember how Heibei attacked the villagers and brought their souls into the spirit world, angry that his forest was burnt. Same principle with the vines.

This episode was amazing, it's just a pity the twist at the end was already spoiled by the trailers.

Honestly, I think "Then where is she?" (from Tonraq) is probably the worst delivered line of dialogue I've heard on the show. But I can't say I noticed much for anyone else.

There was mention of Kuvira wanting that province because of it's ore, perhaps there's some metal-bending scheme underneath her desire to unite the Earth Kingdom

I agree with your views on the episode but I think Korra's more of the belief that she isn't needed as the Avatar and she feels lost without that as a purpose.

"This season has me wishing for an Avatar/Legend Of Korra next-gen video game. Imagine how cool it would be to have full bending control as the Avatar in an open-world action game. And as you level up, you can choose which advanced bending skills you want to learn."
Well, I have good news for you, they are making one…
