I don't understand why we continue to make these kinds of stories, simply put in extremely broad terms, everything experienced from a medium is a form of interpretation, how that comes to us, obstacles (boredom, work, etc.) that stop us from viewing the medium and our own personal preferences make it so that people will interpret differently than others, this is why people who have different views of movies and books will be unsatisfied if they didn't envision that experience from the start (and mostly if they can;t understand elements like budget time etc.).
Heres an example, I hated the first Harry Potter movies, but people who never read the books, had read the books and thought this would be how it would end up, and those who had read the books but were willing to make concessions liked the movies. Several times, what makes people like/dislike a movie over the books has little to do with the fact that books can take more time to flesh out scenery, characters and the world around them, and more to do with what everyone wants to see, You can flesh out characters in easy ways in movies, the director's/developers personal preference/interpretation comes when they remove scenes to add new scenes they made up, or removing characters that hardly affected anything in the major story.
To summarize, it is almost pointless to say that something "is better" than an adaptation, there are things you can clearly point out like competent direction and pacing, because in the long run those who liked the books, and saw only their own interpretation will feel cheated no matter what you put on screen, and those that enjoyed said movie on screen might not read the books because they would feel they are too long, and long-winded.
