Laputa Castle in the Sky, Porco Rososo, Kiki's Delivery Service, Howls Moving Castle are some of the best animated films ever made. No need for Disney when you could watch these instead. I've seen Grave of Fireflies, it is one of the most depressing films ever made, even more baffling when its sister film is My Neighbour Totoro. I heard about the Ghibli museum before, do you not need to book well in advance?
