The Swiss Family Robinson book that I read and the Disney movie based on it are so different in the story and personalities of the characters that it seems to me almost pointless trying to compare them. The book is all about a family getting shipwrecked on an island and the family doing their best to survive on the islands resources and the few provisions they have from the shipwreck. However, the movie has the storyline of a shipwrecked family setting up Home Alone traps while fighting pirates. The characin the movie Jack doesn’t exist, and his character is instead blended with Ernest so that Ernest was more interesting. They also made a love triangle with Ernest and Fritz fighting over Roberta, the movies Emily. The character of the Mother was changed from a happy “we can do well here” in the book to a “this place is so horrible we can never live here under any condition” in the movie. I understand that Disney wanted to make a fun movie for kids, and I think they succeeded splendidly, but it’s not the book. the book was all about the family making inventions and catching animals, which is quite slow-paced and wouldn’t make for a great kids movie. because the stories and themes are so different I think you might as well consider the book and the movie completely different entities that can’t be compared in how well they did one thing or the other.
