One of Hayao Miyazaki's masterpieces, 1989's Kiki's Delivery Service tells the story of a teenage witch trying to find her way in the world. She goes off to an oceanside town and starts up a delivery service. Each delivery has Kiki making new friends that will play important roles as the story unfolds. The story also shares a theme with Spider-Man 2, as Kiki begins to lose her witching abilities while she searches for inspiration as to why she really wants to have those powers. There are also themes similar to the non-fantastical Whisper of the Heart, which also has a teenage girl trying to decide who she wants to be.
Maybe this sounds dull, and while the film is "good old fashioned clean entertainment" (as long as you arent some anti-witchcraft in movies nut), it is actually quite engaging. Like other Miyazaki films, Kiki's Delivery Service contains beautiful flying sequences, a female protagonist, and a leisurely pace. And while the film spends time introducing characters and building relationships rather than trying to stuff in one extra action sequence, there are also some suspenseful moments.
The American dub features the voice of Spider-Man's own MJ as Kiki and of The Simpson's Troy McClure as her cat Jiji. Both of these voices work quite well as does the character played by Janeane Garofalo (who I don't really like in live action, but she was also good in Ratatouille). While not the tip top cream of Miyazaki's crop (a pretty high standard), Kiki is still a gem worthy of an A-.
