All great answers but what I've seen lately is just a lot of whacky decision making. There's multiple video game adaption movies and TV shows come out lately that miss the mark completely. Resident Evil/Halo Etc.
I know adaptations always have their quirks and things that would outrage a fan base but geez. The Halo TV show really felt like they just wanted to write their own story with already existing characters. It all comes down to executive decision.
I just wish the creators have more control over their projects. Instead of having execs with no creative abilities suggesting "Maybe you should make the super-soldier get out of his augmented power armor and instead just fight naked, also make him want to bang the enemy like Romeo & Juliette."
