I thought the movie followed the storyline very well and it was a great adaptation. I liked all of the casting. My kids (ages 8 and 10) nitpicked a few differences but they weren’t really plot-related. The important things were all there (including the animal death, but it felt more brief than it was in the book.)
The one difference that stuck out to me as an adult (and that I loved) was that you could see others’ reactions– particularly Auggie’s Mom (Julia Roberts). Seeing the heartache on her face really struck home for me. I’m not sure if my kids picked up on that part, LOL. Also, I felt like the Middle School Director and Mr. Brown were more fleshed out when you could see their interactions with the students.
What a beautiful story! We loved it.
