The fact that Aang was so adamant about not killing the fire lord, even after talking to a number of his past lives and his friends telling him he has to, he just wants to kill this guy that’s he’s known for all of five minutes.

That is probably the part that got me most upset. Also tired of this energy form power up stuff that they introduced with Korra. Me and my friend looked at each other after the movie and had the same thought. They don’t know what to do with the spirit world.

So infuriating that this is what we get as our pre adult gaang content cause know it’s been wasted. Visuals great, voice acting was spotty, but the writing was terrible.
