The Chip on Katara’s shoulder in Season 1,
The Portrayal of Zuko as an incompetent in Season 2,
The half-assed “redemption” attempt of Azula in Season 3, that didn’t even actually bother trying to show something redeemable about her and instead just gave her a sad backstory with mommy issues to justify not killing her,
The Climaxes to both Aang’s and Zuko’s character arcs being side-stepped thanks to a Deus Ex Machina Entity introducing a mechanic that allows Aang to have his cake and eat it too (even though it actually doesn’t because The Fire Nation doesn’t operate by the same rules as an Ork WAAUGH!), and Katara needing something to do respectively,
AND the subpar and saccharinely hollow building and execution of damn near every canon Romance in the show,
Would ALL like to have a word you.
