How does this argument translate to earthbending in any way? In the original, he stood his ground against a monster, then stood his ground against Toph, all without earthbending. Then she decided that put him in the right mindset, and had him attempt it again, which worked.
In this case, how does getting mad at Toph make him earthbend? Was he overwhelmed with the desire to crush her skull with a rock?
The arrogance of these writers is staggering. I can't imagine being handed something that already functions perfectly on a silver platter and so radically altering it without even thinking for a second about why it was the way it was. For what? Just to leave your mark on it?
You can't argue like so many adaptations that it's time constraints - they have more time per season than the original! It is pure narcissism, the desire to steal someone else's work and "make it their own."
There is a tier of stupidity that makes you a bad person, because you have clearly chosen not to exercise any kind of judgement. If you like this, that's you.
