Paul Elliott’s review published on Letterboxd:
This adaptation of the 1985 children’s novel by Eiko Kadono, and illustrated by Akiko Hayashi, is written, produced and directed by Hayao Miyazaki, who accomplishes an extraordinary responsibility of bringing the characters, including Jiji, the cat, into animated existence for Studio Ghibli. Its storyline involves an inexperienced young witch named Kiki who employs her developing flying abilities to support herself financially, and the animation from the backgrounds to the airborne sequences are spectacular.
Concentrating more on characters, it pleasingly puts forward some incredibly easy to like and entertaining, albeit flawed, figures operating in a world where the fantastical is virtually conventional. It's a great coming of age tale and its themes of self-reliance, responsibility and patience are rendered all the more effective by their modest and delicate delivery. Kiki's Delivery Service is an outstanding animation and delivers plenty of sincere pleasure as well as serving as another illustration of Miyazaki’s inventiveness.
