In short, everything not related to Korra is pretty good, as usual. Sigh.
Bad stuff:
-So what's really sticking out to me in these episodes is the inconsistency in fighting. One moment Korra is a total badass and can beat the shit out of someone, the next she goes down 1 hit, and can't redeem herself. I'd also like to point out a theory I have that her Avatar State is an incomplete one. Aang could take out entire armies and battleship fleets by his lonesome in the Avatar State, yet for some reason she doesn't use it to attack the spirit portal? And she can't beat Unaloq before he fuses with it? Wtf? She also seems to dip in and out of it quite commonly, so something's up here.
-Second, fuck the ending. Seriously, nothing makes any sort of canonical sense/is explained. Okay, I can see why Unaloq becomes a monster when he fuses; he's basically Vaatu but with a human form, and he's super powerful with Rava dead for the time being. But then why can Korra turn into a giant spirit monster? Just cause she's the avatar? Oh wait, she's not. Considering she has a weak spiritual connection and no longer has Rava, there's no reason she should be able to do this. In theory, technically EVERY OTHER HUMAN should be able to do this if she can. It's really just deus ex machina bullshit, and a really dumb way to do it too (giant fighting spirits, really?). And don't even get me started on Jenora, her "help" makes even less sense.
Minor gripes:
-Okay, so Varrick was evil and all, but he was evil for a clearly good reason, no ulterior motives or anything. So then why bother even making him evil? Just seems like a pointless sub-plot to waste episode time. And they make you love Varrick so much, it'd make more sense for him to be seen as good. Nonetheless Varrick is still the best character.
-Korra: "We..don't work together"
*Korra kisses Mako*
Me: "WTF?!" WHAT SENSE DOES THIS MAKE IN ANY WORLD AT ALL?
-Vaatu technically wins, then the first place he goes is republic city, since clearly he knows the entire layout of the earth 10000 years later. Riiiiiiiiiiiiiiiiiiiiiight.
-They went for the "save the day" ending again, despite setting themselves up for a great "Korra loses" ending like season 2 of TLA. They better have a good reason this time.
Good things:
-The humor was spot on from beginning to end. I was laughing pretty consistently every episode this season, so good job comedy writers. Too bad their story writers don't share the same talent.
-I can't say why, but I really love Eska+Bolin. Why can't they just start living together? D:
-Tenzin had more character development in 1 episode than Korra had in the entirety of these 2 seasons.
-Watching Bumi take out an entire camp by his lonesome may have been the best thing to come out of this entire season (other than Wan's story). Also "THE CANNIBALS!" LMAO
-Korra in the spirit world was well done. And seeing Zhao in there was kind of crazy. I'm happy they brought him back, and am suuuuuuper curious exactly how he got there and if he's immortal living there, or is dead and somehow his spirit lives on there.
-Varrick is absolutely hilarious.
-Korra keeping the spirit portals open may have been the smartest decision she's made in both seasons. This definitely has a lot of potential.
-Watching fused Unaloq take Rava out of Korra was fucking creepy, in a good way.
-Though I probably wasn't supposed to be I was laughing really hard at the cheesy slow-mo punch Tonroq did towards Unaloq, and laughed even harder when it failed terribly.
Where will they go from here? They certainly haven't set themselves in a clear continuing direction....again.
