I've noticed it's a good method for Japanese writing. They acclimate you to silly, bashful moments, so that when the writing flexes over to the serious side, it's a big contrast. Yakuza does a lot of that too.

Comparatively, sometimes when I try series like The Last of Us, or even Nier Automata, I sometimes have a hard time buying into the emotions because it's been solely despair for a lot of the runtime.

That said, as I've gotten used to my own creative writing, I see Sky as having tremendous up-moments that give characters some really star moments, but also quite a lot of narmy, amateurish teenage writing especially with the fights, so it gets to be hit and miss.
