There are still some great arcs ahead, with a mix of some uninspired writing. Still, this series is a good adaptation of the original novel.
Its only flaw is the long gaps in between releases and necessary hiatus for the mangaka's health. It is also since been lapped by the anime.
I would still recommend reading this instead of rewatching the first three seasons, along with a rewatch of the season four anime in preparation of the 2024 cinematic anime release.
