Forget it Dracula. I'm with you on the 'Miyazaki is certainly good but what's with the crazy love?' bandwagon, but we won't get any other kind of reply other than 'He's amazing.'
Rumor has it that he really is though.
I find Miyazaki amazing because his movies look gorgeous, and they have such a distinct feel to them. It's hard to put into words, but the way he gives his movies such a grand scale while at the same time keeping them small is simply amazing, something I don't think any other director does on a regular basis. His eye for setting up characters and getting the best look, the best shot, or the more interesting take than what others would have done is second to none. Finally, he creates an entirely unique experience with his movies, mostly through the way he can combine both his visual style and his social commentary or the narrative of the movie until they are almost one and flow completely off of one another. Basically, he is amazing, but I hope that's more of the explanation you were looking for.
