It's great that you enjoyed 'Spirited Away'

I also recommend 'My Neighbour Totoro' for the kiddies. Likewise, you should seek out 'Nausicaa,' and 'Kiki's Delivery Service' when they're a bit older.

I confess, I did like 'Mononoke Hime'/'Princess Mononoke' a bit more for Miyazaki's work, but 'Spirited Away' is right up there too.

If you don't mind watching good & *depressing* Miyazaki, watch 'Graveyard of the Fireflies' ... it's so so so sad. :-(

Well, enjoy!
