Rushed through seasons 1-3 in a couple weeks so I could get here in time.
Season 1 is bad
Season 2 is terrible (apart from those 2 episodes in the past which were good)
Season 3 is OK at best
Season 4 - episode 1
Avatar is a kid's show primarily and this further shows itself here. Continuing with the tradition of the previous seasons there is no sense of nuance or a consideration of the world but rather a rushed boxing in of characters. It doesn't take a genius to work out who will be a bad guy this season the show doesn't at all consider anything that counters it's ideals. The show is already setting up stupid battle lines where Kuviera will be expected to hand over everything to an idiot, just because. And in case that isn't enough they're already showing her in a negative light so I'm sure that she will turn out to be stupidly evil just like all the other enemies. Subjugation for protection is the way the world works. The new prince is as dumb as Bolin but it's clear that the show wants us to think of him in a worse manner for some reason. I don't know the attraction with having this type of character, I've seen spoilt rich kids and whilst they have their quirks, flanderising it like this isn't necessary.
Korra as the Avatar completely ruins the whole point of the role. Avatar's bring balance via FORCE - Roku didn't kindly ask Souzen to stop dicking around, he made him. That Kiyoshi woman avatar split the goddamn continent. Korra now is losing to random mooks. I understand that they want us to show her broken down from her acts of stupidity last season but that is no reason to make her a terrible bender. If little kids can be great benders she has no excuse.
I know it sounds like a lot of complaining but Avatar is stuck in this void, where it wants to deal with more complex matters but feels extremely held back by it's trappings as a show for kids. I don't dislike it per se but am rather disappointed at the amazing world they have that has been consistently broken down by the necessity to build up a new bad guy every season which means that everyone has to hold the idiot ball and power levels become wildly inconsistent just to allow the enemy to become a huge threat and then they pull something out to defeat them at the last second.
