Oh fuck that's a great laugh! Unfortunately I think she's serious. Debunking it isn't hard though, she is saying a lot but... well just watch.
First off, the bullet points. OBSERVE!
What Lily is writing is the Disney-fied version, it used to be very cut and dry. Also she fails to "de-game-ify" KOTOR so she thinks the press a button to le good boy points or le bad boy points is intentional. It's a game Lily, the game will kiss your ass no matter what you do, because game.
Extreme failure to recognize gamey elements, "muh horde champion is gruff an' tough an' don't take no shit from nobody!" That's nice ma'am get to the back of the line with the 4.5 million or so other horde champions that all say that. You ain't special.
There isn't a formula. Avatar is not a franchise large enough to have become formulaic.
From here it's basically using way too much to say far too little. Yapping that she's being deconstructive and lookit how smart she is!... Except she didn't and hasn't done a deconstruction of anything. This runs parallel to a Learning From Lorch I'm working on, but a key part of a proper deconstruction is knowing and caring about the original thing.
Lily does not. She likes things from them, but the unbroken whole can kick sand. There's no deconstruction unless we are talking entirely literally in that most of the vehicle that is storytelling just isn't fucking there. Niva is made to hard counter Ozai types... though ACTUALLY doing that implies Niva is active enough into politics to find and expose them before they gain political power, which uh
She talks about hating being the Avatar but in her entire tenure she's only ever beseeched about 4 times in her whole life to ever do anything, and it's always an Avatar level threat. Not even mentioning she accrued more raw bending power than any previous avatar! "I hate being the Avatar so I will now become the most powerful one to exer exist ever" logic checks out, yeah. Which fucking sucks because Aang is already a beautiful deconstruction of the chosen one archetype. Niva is in every way worse than Korra while falling into all the same traps!
And to address the asker, who claimed they're all just mean heros....welll...
It's that heroic deeds on paper does not equal being heroic. Niva again exemplifies the problem most, and boy do I have receipts!
Only truly tries against a terrorist group once her sister is at risk of being a casualty of war.
Lackidaisical attitude towards ARMAGEDDON.
Decides to make more statistics out of innocent people while demanding that the world leaders apologize for her HURTING HER FEELINGS...
Struggled for a THIRD TIME to account for innocent people in a crisis! This is no hero, this is a fucking psychopath.
