In fact, the transition from Point A to Point B is actually the big “hook” of Kiki’s Delivery Service. It isn’t just that Kiki is cast down from heaven because she can’t fly anymore, it’s that she is the only person in a fairy tale kingdom who thinks that being alive and awake is a good thing, that she might have a higher purpose than simply playing tea party in her garden. She is, ultimately, the star of Kiki’s Delivery Service in the same way that all children desire to see the world as such star children do, you see. The movie does not suggest that Kiki is going to grow up to be an elderly lady with a couple of cats in her tiny London flat, or that she is going to spend her day gossiping with her hairdresser, or that she will pursue a career as a diplomat or run a cat-themed hair salon. But that doesn’t mean the story doesn’t try to place her in those roles. However, World War II really does happen, and Kiki’s father gets in the middle of it. And although he’s Kiki’s biological father, he is most likely the earthly version of the fairy tale king, Hokke, and not her real father. And when it’s all over, Kiki goes back home, and she’s still a child, full of wonder and good childhood memories. She may end up flying someday, but for now, Kiki’s Delivery Service is about her coming-of-age (wonder, remembering childhood, the loss of one's power, a higher purpose) in a way that is far richer than simply “famously doubting” that she can fly anymore.
So, let’s talk about this in a very frank way. Kiki’s Delivery Service is a wonderful movie. It does not just try to make you miss childhood, as Robin’s commentary says above: it gives you that perfect moment where you remember what you were like as a child, seeing through your own adult eyes and mind, seeing themate! The movie is a glorious reminder of why we love fairy tales so much.
