Sadly this setting is poorly developed and most of the comedy that made the drama watchable and at some point enjoyable at season 1, is gone.
Confusing dialogues:
During most of season 2, in an attempt to depict the social opening and inner struggle of the main cast, they created inconsistent personalities and dialogues. This mixed with the short amount of episodes per season and rushed story, ended up with a show that is hard to understand.
Season 3 takes the difficulty of understanding the dialogues even further. First because they are talking about more complex subjects than previous seasons. Second, because you have to remember a lot from the previous seasons and you have to read forums to fill some plot holes. Third because it got so cringy to read what they are saying that it becomes an obstacle.
Original plot is gone:
In season 1 and some part of season 2, there was a different plot and pacing, so the drama was exposed softly and was endurable. Now that is gone, this season is even more dramatic than season 2. You won't find the silly group of two antosocials, a silly girl and a violent teacher that solved the problem of the girly tennist or the insane novelist, anymore.
For me, this was one of the worst things, because even with the confusing dialogues, I had fun watching the characters doing their stuff and the silly love triangle starting to bloom in first season. If you take that out, and leave the rest you have nothing.
The way they treat Hachiman, and how it all feels so unreal:
I think that they treated him better in season 1 though.
Sometimes I feel bad for hachiman because they say in his face he is ugly, that they hate him, even his sister and the supposed waifus.
So If this plot intends to depict some degree of real social interactions, I don't understand why Hachiman hasn't left everyone for treating him that way.
Confusing dialogues 2:
I am not exaggerating, all dialogues are like the last dialogue from season 2. You remember how you were happy to understand a bit of the story decoding the dialogues and at some point in the last 10 minutes an avalanche of nonsense ended it? Well all dialogues feel like that sudden not understandingness.
Age of the viewer:
Even if you are a teenager, swimming in the endless sea of depression and hormones of your age, you will find painful to watch the dialogues even if you can bare the over exaggerated drama.
Conclusion:
I don't recommend this to anyone even if you want to see how the story ends. Because you will be better reading the end from a forum, you won't expend 12 x 20 minutes of your life trying to understand the dialogues, your time is more valuable this show doesn't deserve your time.
It is sad but happens, and one has to learn when to abandon an anime because it sank itself in its own trash.
