Trust me, having grown up in the countryside, time going slow is not an unadulterated joy. In anime form it is indeed relaxing to look at. Relaxing is the keyword for Flying Witch. Not so much Kiki’s Delivery Service as Non Non Biyori.
It takes ten minutes for the Flying Witch to actually fly. This is a very slow anime. But not a dull anime. it just takes its time with everything. Nothing much happens other than that the titular witch moves to the country to live with relatives, goes to her new school and gets to meet the childhood friend of her cousin.
Anime is not often subtle with showing emotions and expressions. What makes the reaction shots to seeing our witch fly so funny is how understated they are, as well as how slow the childhood friend — and earlier, the cousin’s younger sister — are to react. And how low key and natural the responses are.
