We all suffered as kids when TV shows dragged for too long when the authors ran out of ideas — Dragon Ball Z I’m looking at you.
Manga cuts through all of that. You can simply skim through the filler much easier.
I’ll concede that, some times, manga slows down too. But it is orders of magnitude more tolerable than, say, anime.
The mangas that got me hooked where a combination of old and new: Junji Ito stuff, Berserk, Claymore, Chainsaw Man, The Way of the Househusband and Dorohedoro. I know that I just mixed some of the absolute best works of art that you could find in the format with totally mid and forgettable stuff, but that is the good thing about aging — you do not give a fuck.
Guts and Casca in some kind of fluffy romantic comedy setting. Those two deserve a rest.
