(From the perspective of someone who read the books first)
I didn’t even finish the movie, it was that bad to me. There are a lot of little things, I could make a whole list of all the stuff they got wrong but there are already a bunch of reviews doing that for me so I’ll say this, they took a side note from the book, and centered the plot around it, then basically hacked the rest of it to pieces, and made that into a movie.
