The real problem with books-turned-movies isn’t “omg they didn’t include every single word in the book” it’s “omg they completely overlooked the main theme, threw out any significant allegories, took away all the emotional pull, an turned it into a boring action movie with a love triangle in it”
the hunger games is a really good example bc on the base textual level of stuff like what happens and the order of events they got it mostly right but they also
whitewashed half or more of the cast
removed multiple canonical disabilities in main characters
marketed it as a love triangle
basically did literally everything the villains of the book did which made it super fucking obvious
