There are many changes from the book (The Little White Horse by Elizabeth Goudge).
I thought the ending they invented was a lot more effective than the ending in the book.
However, I was very disappointed with how they changed Robin’s character, and cut way back on Maria and Robin’s partnership and completed eliminated their romance.
Many subsidiary characters were eliminated as well. 
It had Humour and excitement it was just overall a good movie!
The characters Miss Heliotrope and The Chef were awesome.
I can’t wait for everyone to see this movie its really good!
The acting was fantastic by the way!
enjoy!
