It's been at least 20 years since I read the book, so I can't comment on the fidelity of the plot (which will always be different from book to movie). Despite a pretty stellar cast, the dialogue feels very unnatural and scenes don't seem to flow well. My biggest beef though is the animation and rendering style. I was genuinely shocked to find out this movie was released last year! It seriously looks like a video game from 10+ years ago. The lips move strangely, more like they are morphing and contorting than forming sounds and expressions. They tried to give it a "painterly" look, but it just feels cheap and low fi. Pretty disappointing.
