I've seen his early works (Lupin Sansei, Future Boy Conan) and some of the recent stuff (Nausicaa, Grave of the Fireflies, My Neighbor Totoro, Spirited Away). His anime are truly pieces of art, and he always carry a meaningful message on all of them. He is a brilliant director, and knows how to cativate an audience and to hold their atention. Take "Nausicaa" as an example, it has a slightly complicated plot and it takes time for the viewer to get every information about the characters and the world they live in, and he does this brilliantly, in a +2 hour anime without boring the audience or confusing it.

So, if you liked Nausicaa, watch "Grave of the Fireflies". I'd like to discuss it with you
