I feel there's this trend where movie directors must and shall make their own story in whatever world is in front of them, instead of trying to make a movie that would fit in the game, or simply take the game's story and make a movie out of that.

It's why Lord of The Ring was so fucking good (Christopher Lee/Saruman read the books every year of his life, and corrected Peter Jackson whenever necessary), whereas Rings of Power is shit (I mean, a loving Orc family? What the FUCK have they been snorting!?). It's also why I'm hopeful to get something good out of Henry Cavill directing any 40k movie (that, or we're getting nothing, at best. At worst someone else takes over and we're getting female custodes for no good reason).
