The anime is a constant bretrayal of the things it wants to tell, the author clearly has good ideas but his excecution is just really lacking. The serie is just not focused, what does it try to say? You can try hard to overcome things, yeah if a weird guy comes to you and gifts you a power, heroes are good and needed, yeah if you ignore all the violations they do and how frugal they treat other heroes lives including that of teens. The villains are in the right then? Hell no, one of them wants to genocide all non powers, other wants to kill everything and everyone, other wants to dominate humanity, it is just plainly bad things without much characterization.
Now lets go over specifical things of the season which dissapoint me.
You got tomura with the most tame backstory and trying to justify constantly he is just a product of the enviroment.
You got off screen deahs of dozen of heroes instead of anything that might impact the watcher at all.
Society turning on heroes for what is the tamest things possible, they only have two reasons, a killing of a villain that was gonna kill people and the son being one of the villains, thats it, and the fact that "oh you didnt protect us so dont protect us anymore", instead they could have perfectly made it so more classes participated into the attacks, which would make more sense than only class 1-A and B, with all of two and three years missing apart of the three seniors, make it so students die and now the media has a reason to hate heroes institutions, but oh well.
I still have no idea why they didnt just kill all for one in prison, surely aizawa could show up, erase his power and they get something to chop his head or something but okey let this guy that has been 100 years terrorizing socierty live because no reasons.
I dislike the direction of going towards more quirks for everyone, it doesnt feel at all earner for any party and the fights are just a mess.
Really dont know why the author idea of a long time is a week, hawks infiltrates the enemy surely he has been doing it for months atleast no? Nop it was just less than a week, midoriya has been training after the heroes collapse for a while to get a hold of his new powers for sure right? Nop just 3 days. Surely the anime will use the fact that the academy is 3 years long and not just cram everything into a single year, nop lets fucking go year 1 baby.
