what wound du have chnaged if you were the crator of the owl house
oof, where to even start. there's a whole BUNCH of things i would change.
first off, Belos. i would expand on his story a bit more. there's no need to show EVERYTHING, especially if i'm under the same time constraints as the writers, but i would ditch the Hexside subplot in S3 to focus on Belos and his backstory, giving the audience more of an insider perspective on what actually happened, rather than letting a random kid tell his story and end it with a corny ass joke (sorry, Masha, but that joke about Belos being jealous of his brother getting laid was... unfunny. it had potential but it was just worded in such a lame manner imo).
i would also make Belos's ending more cathartic and less anti-climactic. i have no problem with him dying, it's the way that he's killed that's super unsatisfying. it's like the creators just ran out of ideas and was like “haha what if he pleads pathetically and gets killed by the rain”.
i think a better option would have been if people from the human realm saw Belos in his monster form, and were absolutely terrified. maybe in the process of trying to defend themselves, they set fire to him, mirroring how witches were burned during the Puritan era.
that would have been a lot more cathartic and would have tied into his character better. it's a classic Greek tragedy format — character who throws all of his morals away and dedicates his life to an evil cause, only to get killed by his own horrible actions. it would honored Belos as the layered villain he was.
next up, Huntlow. i would either write their relationship a little differently so they're both not so horribly mischaracterized, or i would simply not make Huntlow a thing.
honestly, i always headcanoned Willow as aroace, since she never shows any level of romantic interest or attraction towards anyone. even with Hunter, her blushing and shyness felt extremely out of character.
but if i were to write them as a couple, i would simply keep their personalities the same, apart from the necessary character development of Willow becoming more confident in herself and Hunter healing from his trauma. Hunter can still be sardonic, witty and a bit of a menace. Willow can still be level-headed, responsible and kind.
and Willow can still have her heroic moments and be a badass without having to constantly rescue Hunter, a child prodigy who had to endure various trials to become a seasoned fighter.
in fact, i would instead put them on the same level, and have them fight side by side, protecting each other's backs. kinda like Steven and Connie from SU or Puss and Kitty from The Last Wish. that would be a lot more fun to watch, and would help build on their chemistry a lot more than whatever happened in canon.
another thing i would change would be the Collector. they went from being a malicious entity who laughed at the sufferings of mortals to bring a goofy little kid who's just too innocent and dumb.
i don't know, i feel like the writers should have stuck with either one of these characterizations. either make him an immortal child that doesn't know what death is, or make them an evil eldritch god that just doesn't care about these things. you can't do both.
and the rushed redemption arc in the end was also... bad. not as bad as Catra or the Diamonds, but bad regardless. i love how fans of TOH praise it for not redeeming its villain, when it did do that, just not with the main villain.
speed round! i would make Amity a more interesting character independent of her relationship with Luz, and not change her personality entirely.
i would make Lilith's redemption arc a little slower and let her really earn Eda and Luz's trust and forgiveness.
i would make Luz's palisman something actually interesting, instead of desperately trying to subvert fans' expectations while also referencing all fan theories.
and on that note, i would make Luz's big revelation something other than the extremely vague “i want to be understood” because she WAS understood — by Eda, by King, by Amity, by Willow and Gus and Hunter. i don't really get the point of this scene.
i think that's about the changes i would make to TOH. there were some other minor stuff but they're not that bad really.
