The characters and plot have been changed. In the books the children are polite, show good sportsmanship and most of all, good seamanship. The children in the film are rude, whining, brats who can't sail or camp and keep arguing with each other. The plot of the books is a delightful innocent children's adventure, the film has added a spy plot that negates any sense of childish wonder or joy.
