Miyazaki is an amazing Japanese film director, animator, artist, producer, and screenwriter. His animation will take your breath away, just as much as his charming stories will.
The entire screenplay is masterfully written. The characters and settings, whether they are frightening or endearing, are beautifully drawn. This film, as well as all of his films, is full of adventure, mystery, and wit. He does not write typical "evil" characters; nothing is black and white.
I highly recommend any of his films. Don't expect the animation to be the same as classic Disney, it's a completely different style. Look for the wonderful settings, charming characters, and creative writing. You won't be disappointed.
