Nah, its bad writing. Rushing in film usually means that characters spent way too much time talking doing exposition. Also the fact that time passing is never represented, so it all just feel like one long day that never moves forward in time.
On my part I don't want a perfect adaptation. Or a frame to frame adaptation. That would be boring and would never work on live action. I want good writers to do creative adaptations of the world that use the strengths of the medium to produce high quality entertaining new stories. If I want to see Aang story again, I will prefer the original animation instead every single time.
I appreciate this adaptation for what it is, and it is rather mediocre. Not bad, not good. It just exists.
