An unpopular opinion: I like LOK more than ATLA.
- In ATLA, there is one main villain: Ozai. A typical power-hungry overlord who wants to take over the world. Korra deals with a whole spectrum of villains, all of which are more relatable than Ozai.
- I prefer the pacing in LOK: 4 shorter seasons rather than 3 longer seasons. 12 episodes is enough to accomplish all the season’s goals and still throw in some random stuff for fun.
- Gaang can be described as a group of early teens travelling the world and having adventures – with hardly any supervision from adults. I know they were forced to grow up fast, but to see such young people fighting in a war makes me sad. I am more comfortable with the older cast of Krew dealing with this kind of stuff.
(This one might be a psychological thing. When I was 15 I wrote a story about teenage modern ninjas (inspired by Naruto, yes) and asked my father for a review. He liked my writing, but was not okay with the concept of children wanting to be soldiers. 11 years later, I suppose he was right.)
Also, for the record: I did see LOK before ATLA. With the exception of season 4, which was still a work in progress.
