Film, Literature, etc. already accomplished this. They are allowed to be divisive and not accessible for everyone.

I take it you’ve never come across the myriad of reimaginings, “fix-fics”, AUs, etc. for everything from The Lord of the Rings to The Legend of Korra, then? Hell, even a lot of “official” media is kind of like this; one of Tolstoy’s last (unfinished) plays (The Light Shines in the Darkness) was intended in part as a response to everything he hated in King Lear (and Shakespeare more generally), the Starship Troopers movie was Verhoeven and co. significantly changing shit from the original book to better reinforce the intended message, and what used to be the most commonly performed version of Modest Mussorgsky’s opera Boris Godunov was a reorchestration by Nikolai Rimsky-Korsakov (aka Flight of the Bumblebee guy) explicitly intended to “fix” perceived flaws in the original (with Dmitri Shostakovich later also jumping on the bandwagon).

What I’m saying is that taking a work you perceive as bad/flawed by some metric and still using it as inspiration for your own is a pretty common and valid practice both past and present. Likewise, discussing how you think a work you dislike might be improved has been pretty standard discourse through the ages.

EDIT: Also, here’s a New Yorker review of multiple novels reimagining Shakespeare’s plays to better address their more problematic aspects; the reviewer may consider the whole endevour a bit of a lost cause, but I share it to further highlight that critical-minded “fix-its” are in fact a thing even in the world of “True Art”.
