Oh gosh, I have SO MANY! Don't know where to start...

So off the top of my head, I'd say:
Loved the TLoTR books, liked the movies (and even some video games), but HATED Amazon's Rings of Power. Changing Tolkien in any way is like when they painted clothes over the nudes in the Sistine Chapel 'cause some deemed them "too naked" LoL.
Loved The Witcher books, also the comics and videogames, but HATED Netflix's Witcher series with a PASSION. To me, Netflix's Witcher is just like the famous "restoration" of that 19th century masterpiece Ecce Homo into a hideous hellspawn (thus dubbed "worst art 'restoration' of all time").

I think Henry Cavill is actually the secret identity of the real Superman, he's just not interested in saving humanity, especially after he was bullied away from The Witcher and, well, Superman.
I didn't love but didn't dislike the Harry Potter books; I find the movies entertaining, and Hogwarts Legacy doesn't seem like a crap game to me, but a title with some very respectable things (for example, the work of concept artists, char designers, animators and vfx, music, voice acting, etc.).
MMORPGs scare me, and depress me, especially those with cute fluffy mobs, or those where you have to kill tons of wildlife. What's more, I hate it when RPGs have cute monsters, like fully rabbits, smiling slimes and the like. Also hate when in videogames or anime monsters/mobs are animals, like a giant turtle (why!?

), or anthropomorphic enemies with cute faces of wolves, cats, deer, horses, etc. No!
Conversely, love games and anime in which animals, wildlife in general, are Not grinding mobs, but rare encounters, and in which monsters are either humans, really scary humanoid abominations, truly demonic monsters, so there's a reason to fight them, 'cause they're really gross evil creatures, idk, like demented ghouls, sadistic goblins (GoblinSlayer did them right) that pose an actual threat.
Oh, I also think that eating cats and dogs and dolphins and anything with capacity for feelings and empathy besides moral and physical suffering is beyond vile.
