Was it on this morning? I forgot to look for it.
Wow, you mean you haven't restructured your whole life around making sure you don't miss a moment of Korra
It's on again at 3 PM Eastern today (Saturday), as well as 7:30 AM and 8 PM tomorrow, Monday at 4:30 PM, Thursday at 5:30 PM, Friday at 8:30 PM, and next Saturday at 8 AM.
Since you haven't seen it yet, I'll spoiler-code the big stuff.
Wow... that was amazing.
Amazing is a pretty good word for it. I was concerned that the first two episodes didn't do enough to spell out the stakes of this series, but this one more than made up for that. It was very powerful.
As for the former, that was exactly what I expected -- that they'd use lightning-benders to create electricity (which is hardly a major spoiler, just a background detail). What is interesting is how common the ability seems to be. Seventy years ago, lightning-bending was a top-level skill that, as far as we saw, was possessed only by members of Sozin's dynasty (Ozai, Iroh, and Azula could generate lightning; Zuko could only redirect it). Now it's become much more commonplace. Which is similar to the proliferation of metalbending since Toph first discovered it. I wonder what reforms and institutions Aang, Zuko, and their allies put into place in building this new civilization that enabled such high-level abilities to proliferate to this degree.
But then, maybe it's just an improved educational system. There are analogies in our own history, a lot of things (like literacy or computer programming) that were once the disciplines of an elite few but are now far more universal. An increase in urbanization brings more people within reach of higher education and advanced knowledge, and improvements in communication and transportation allow knowledge to be spread faster and more widely. So in the Avatar World, advanced bending knowledge that was once in the hands of a few great masters spread widely around the world, and therefore only accessible to a limited few, may have become more common knowledge.
