It's tough but the books were better by a small margin. We go into the history more of the characters and the historical accuracy was amazing. Still, the movies were the best book to film adaptations I had ever seen. Some differences, yet, but for the most part stuck to the story. Orry living through Book 2 was the best part. The ending with all walking away from Mont Royal w/ regrets but looking forward to the future worked perfectly.
Book 3.....gotta go w/ book. I didn't like the fact Constance was murdered and George's feelings for Madelline could have been handled better, but it had so much that didn't get put in the movie. The book goes to 1877, includes Charles and Willa's future and the families. It was my least favorite by a long shot and have only read it twice (the others multiple times), but Heaven and Hell was 10 x better than Book 3 miniseries
