Director Hayao Miyazaki is a master; this and My Neighbour Totoro are my favourite Ghibli films - they benefit, I think, from their relative narrative simplicity, whereas for me Howl's Moving Castle and Princess Mononoke despite also being high in the Top 250 are too complex and therefore don't hang together as well. (They are also darker in tone, which might be another reason I like them less.)
Incredibly, this film was apparently made without a script - the plot and characters developed organically via the storyboards.
Well, Miyazaki may finally have retired now (after five decades in the industry), but I still have plenty of unwatched Ghibli films to enjoy.
