The movie seems to ramble on for a good portion of the series, so you have to have patience. Dorothy seems to be more than a bit lost and confused. How she manages to keep pressing forward to the end mystifies. Most people in a similar situation would probably resign themselves to their fate, and settle down to a quiet life in the face of so many threats to life and limb, but the story would not be the same I suppose... But press on she does, and quite a few times I wondered if it was going to be worth it to see it through to the end myself. Kids will probably leave to do other stuff at some point. By the last installment you begin to see the "why" of it all, but you still don't know how it will all turn out, but it will be predictable all the same. If I had to choose, I would pick Judy Garland every time, and so would your kids, I imagine.
