This was a pretty impressive episode, but I'm getting tired of Korra being an idiot. I guess I can understand that she's angry and worried about her family, but she's just ignoring everything her mentors have told her. But no doubt that's why that spirit was angered and why it attacked her. She's on a destructive path and needs to be set straight. Which I assume will be the point of the "Beginnings" 2-parter which starts in two weeks, but before that there's an episode called "The Sting."
Still, we got to see more of the world, including a strong showing by President Raiko, the police station where Mako and Lin work, a return to the pro-bending arena, more of Varrick's life and work, a return appearance by General Iroh, etc. I wonder if Korra will actually get to the Fire Nation next week, or if her enforced spiritual journey will divert her.
Tenzin's subplot with Meelo was kind of nice, but not as impressive as what we got last week. The best bit was when Meelo said "Being the alpha lemur is lonely" and Tenzin said, "I know."
Apparently the reason for the time-slot move is that the 7 PM slot was a "ratings graveyard,"
according to Bryan Konietzko. But it's still doing quite well on iTunes and Nick.com. So we probably have nothing to fear. I was a bit worried a few days ago when io9 mentioned a rumor that Nickelodeon might be dropping the show and moving it to NickToons, but probably that was a misunderstanding of the planned time-slot move. (Although the advantage of NickToons would be that it doesn't have the persistent audio dropouts that Nickelodeon has on my cable system.)
I believe the eye color bit was invented for the Korra series.
No, it was very much present in A:TLA as well.
Asian Teddy Roosevelt was an interesting character; how come this character didn't exist in the first season when the Equalists were taking over Republic City?
Because at the time, the executive branch was the Council instead of a president. They've changed the system. Though it's a fair question what Raiko's background is and how he came to be president.
So, where is the Earth Kingdom then? Because the Republic seems to exist where the Earth Kingdom used to be. Is the primary continent on Avatar world split between the Republic and the Earth Kingdom?
The United Republic occupies the territory of what used to be the Fire Nation colonies in the western Earth Kingdom. The comics show how those colonies had come to be multicultural over the decades of their existence, with Aang and Zuko originally trying to dismantle them but then realizing that despite their origins in conquest, the new society that had evolved there had a right to survive. And that was the foundation of the United Republic.
