I actually just watched the entire series over the past week. I gotta say, I was disappointed overall.there were moents here and there but too far and few between. Despite being a more mature age group, the storyline had a smaller scope and was less serious than ATLAB. Initially, I thought Korra was a refreshing take on the new Avatar. Someone who was head strong and rather aggressive that would get her into situations that require more than brute power as opposed to Aang who was completely opposite due to that aggression being against Aang's Air Monk teachings and needed more spiritual based power. However, she routinely was overpowered by people who she should not have been. I liked how she would be willing to start a fight rather than run from one but the problem was that despite being more versed in her usage of bending, she came across weaker overall.
In fact, I thought the power scaling of all benders in the show were noticeably weaker than the originals. Almost as if they intended to nerf bending in order to make the non-benders more threatening. The scale of flames were smaller, the earth bending was smaller, the water bending was damn near non-existent with the exception of Amon but his power almost seemed non-canon dbz movie status. He was able to take people's bending and bloodbend yet the power scale as to when he used his waterbending was not significant enough to warrant that level of so-called mastery. shyt like that is what pissed me off about the show. They lost the spiritual and martial art side that made the original better and the benders better I think by having this Industrialist Age come about and maybe thats why the power of bending in general is nerfed due to the lack of spiritual connections. Or maybe, it was just animated in such a way where its smaller. Who knows, I just know it bothered me. Korra, despite having mastery of 3 elements for almost 18yrs was losing to regular ass benders and getting that work from non-bending martial artists. Aang, having absolutely no mastery of any element other than Air would not lose to even top tier benders. Its just weird to me that they would do it like that. I would say, Korra should be more versed in bending since she was bending fire, water and earth as a toddler and should also have more power being a brolic as hell and 5-8 years Aang's senior with extensive Avatar specific training for 15 years, where as Aang had none.
Benders in LOK seemed more advanced in regard to specialty techniques that were either created during Aang's time or rarely seen though like metal bending or lava/lightning (to a smaller degree) but lack the raw power of the originals. There were times where Korra was obviously nerfed for plot reasons that made fights stupid to me. Much of it was her fragile psyche even from first seeing Amon take bending away. She was more scared than she should have been and spent the next 3 Books being aggressive against scrubs and timid against the real threats. I personally enjoyed the fight she had with Zaheer when she was hopping around like Ozai because she had brief moments of being that predatory before the poison kicked in. Other than that, she was weak and fought with no technique. She should have washed everyone except for when she was poisoned and it affected her but she lost to random henchman too much. Silly stuff like her weak airbending during the fight with Kuvina yet, two non-master airbenders make a tornado that holds off the entire army, Kuvina included. Its just too inconsistent to enjoy the fights. So im left with the story and that was not as well written as I would have liked. Mako's interactions with Korra and Asami was kinda funny most times and Toph's daughters stories were cool but not expanded enough on. Beric and Bolin were comedy but aside from that, not that interesting. Then the whole lesbian thing at the end seemed out of place but I didnt really care at that point. Korra had tons of potential for writing as a character. She was a strong woman with a drive but was also a late teenager becoming a woman and they jut barely touched on that. It was an enjoyable show, just not as heavy as ATLAB despite trying to be. It was never able to elicit the emotional range that ATLAB did (mostly due to Zuko's storyline). It did a little bit when Amon's brother killed them. That was a powerful moment I think but the highlight of the show was the Wan Arc which had nothing to do with Korra. Unfortunate.
