Since others here have said it, this delightful!! movie may not be a 100% representation of the book. I don't know, I don't read French and apparently this was a French book of some repute.
So?
Charlton Heston in the Ten Commandments certainly did not portray that book (lol) 100% accurately. Yet, a lot of people for decades have enjoyed that movie.
No, this isn't on par, but, this was a very nice movie, with no parts that were NSFW. And today, that is something different.
Watch it. For just easy entertainment value, 10 out of 10. As a movie overall, 8 out of 10.
