Read the novel, it was a bit meh to be honest, so when I heard that the movie version is a lot different than the book, I was intrigued..

no joke, Spielberg (or the writers) changed almost 70-80% of the detail, however, it made the movie a lot better than the novel, 8/10 from me

2 minor gripes about the changes though:

ya I understand that he couldn't get every rights for every character he intended to put in the movie that's why its just a small gripe for me, however
