So the moral of this movie and the book is...
to be wary of strangers. But then again Roald Dahl's books always had all kinds of morals to them that are dealt with in society.
shareI don't think there was a moral to all of his books. What is the moral of The BFG? Beware of giants coming for you at night to eat you?
shareWell not all of them, but some do stick out as kinda preachy.
Charlie and the Chocalate Factory: taught us not to be like those four other children with Charlie, who were spoiled, gloutounus, ill-mannered, and being desensitized/mentally degenerated.
Matilda: also showed us the benefits of reading a lot and how degenerative and loathsome her family the Wormwoods were towards reading and the educated.
Didn't you notice the parallels between what those witches do and what you hear from your parents about strangers as a kid?
The Witches, take a lot of cues for children not to trust or approach strangers, for fear of them doing harm to kids. The biggest one is the whole candy bit, that they may have laced with something bad that they try to offer to children. It may not be magic but it is true that some sick people have tried poisoning kids by offering them candy.
