I find it interesting that a single director is able to receive so much attention while there are so many very wonderfully epic anime films (movies without an animated series backing it).
Although I have seen several Miyazaki's films, I can't say I love every single one. As a matter of fact after you've seen two or three of them they start to get quite repetitive.
Despite that, I must say that I have placed one or two of his films on my top favorites list.
First one is Princess Mononoke -his all-time masterpiece
Second is Kiki's Delivery Service.
Third is Laputa: Castle in the Sky. (Main reason- Hideaki Anno started his career working with Miyazaki while working on this film.)
Spirited Away was okay, but not especially a fan. Although for those who ARE fans of this film, I would like to suggest (if you haven't already seen it) "Kami-Chu!" a 16 Episode anime created by Aniplex that follows a very similar theme as Spirited away.
