I started reading Bnha after the first season ended, it was around chapter 70/80 I think. But all my hype went down during the Overhaul arc, then went high with Endeavours arc but then again with Class a vs Class b, that aside of the 7 quirks, Momo's performance was terrible and disappointing. I decided to drop it, then I picked it up again with Villian arc and I'm still reading it.
One of the aspects I dislike the most, is Bakugou, I dunno, that image of him from the first chapters as a bully, kinda stickied to me. I know the guy has improved, but that image won't be forgotten that easily, at least for me.
The other one is the bunch of characters. I know these will be developed in the future, but it will take only a few chapters to shine and then dissappear. Do you know a fellow called Iida? I forgot.
Of course it has his negative/positive aspects and I cheer the positives ones like the art, development of some characters and the comedy.
