Totoro is still my feel-good movie of choice, and I second the rec for the kidlets and grownups. That movie got my monster truck and football loving three-year-old nephew into Miyazaki, though he calls the totoros 'bunnies,' just to make me laugh. I just watched all of A:TLA for the first time in these last two weeks (thank you, Netflix!), and I may have squeed "catbus!" when I saw Appa. If the Catbus and the big Totoro had a lovechild who could airbend, you'd get our big squishy sky bison.
