I'd have added around 3 more stars to this review if they had poured the manga in, just as it was. But no, no. They had to milk it, and to do so, they added a dumb amount of fillers. Every season. Which makes this anime sort-of unwatchable. If you want to watch it though, I'd suggest to skip the filler episodes (there must be a guide somewhere.)
Pretty good anime. But yeah, 1 star because greed.
