Common Sense Note
Parents need to know that this movie is not for younger kids. It's very violent, with lots of destruction and a father trying to kill his son. It shows a society being transformed by scientific leaps in steam power. You might talk with teens about how electricity and now computers have done the same, and whether some humanity has been lost along the way. You might also take the opportunity to do some research into real-life wonders of the Great Exhibition, like the Crystal Palace.
Plentiful destruction, even if the body count seems ludicrously low. A father tries to kill his son.
The young and resourceful hero is a good role model. A bratty rich girl (named, if you can believe it, Scarlett O'Hara) is less admirable, but seems to change her attitude by the end.
