The story is a little different from the book (of course!), but it had been a couple of years since we read the book. We all enjoyed it, and my budding engineer particularly enjoyed all the contraptions depicted. My kids enjoyed the "making of" section on the DVD from Netflix. There were a couple of times when non-villain characters lied: the Lender boy offers one lie after another to his parents to get them to stop the moving truck. They suspect him, but nothing comes of it. It's not even a story element, but the movie ends with, Arietty telling her mom that she's just "going out in the garden" (or something) with her new friend, while hiding walnut shells for a fast car(ish) ride behind their backs.
