@Ultimaniac There's slice of life and slice of life. Some slice of life just naturally isn't going anywhere much--there isn't a real plot, the characters don't have any obvious objectives, so it just noodles along. Some of my favourite manga are like that--say,
Flying Witch or
Yotsuba.
And there's slice of life that are getting somewhere, but v e r y s l o w l y.
Yesterday wo Utatte was like that, for instance--a lot of steps forward and steps back, a lot of stuff that only glancingly touched on the question of plot, but ultimately the characters were working through personal stuff, coming out the other side, and in the end resolving the romance. It was occasionally frustrating but I loved Yesterday wo Utatte.
Then there's "slice of life" where the characters do have an objective, it's fairly simple and direct, and the reason nothing happens is that they can't be allowed to reach it or the manga is over. So almost every chapter has the pattern "Try to reach the objective, appear to make progress, be frustrated in the end and return to square one". This is one of those, and it's a pattern that gets stale. Literally none of my favourite manga have this approach, although some come close-ish. To be good they have to make up for the structure problem by being
incredibly cute. Like that one with shogi-playing tiny sempai.
