End of paranormal war arc
the main problem from season 6 happens after the paranormal war arc, this is when the writing starts to drop miss midnight just died in front of a squad and after the war there's no funeral or any mourning even by the characters who she inspired like kirisma and momo. Another problems is that when hawks gets exposed for his murder of twice none of the heroes react to this only the citizens , tokoyami questions it once then acts like it never happened. Also same thing happened with endeavor only todoroki and his family questioned endeavor about his abuse on Toya. In short it's like only the citizens reacted to everything , none of the heroes did.

tatarus escapee
this first point is when gran torino lives , full power shigaraki demolishes him but he lives , would of been more impactful if he died and left his scarf for deku to use. This is the start of when the writer doesn't kill off characters. Apart from that this arc is fine until ep 22 the manga had same issue. There is barely any time for us to take in that deku is by myself after leaving all might because right after class 1a find him. I wish this bit was longer by an ep where it's just him dealing with crime then 1a finds him in the next ep and it feels like deku got tired from doing barely anything (deku vs muscular , vs lady nagant). i love the 1a vs deku fight. The final problems is how bakugo's apology is taken as if it never happened this can be seen in the final ep when they are in the bath , deku doesn't even talk with him about it at first he didn't because he was tired which is fair but this time he is right in front of him. The same issue is scene with deku's apology to all might and all might's apology to him, they play it off as a comedy scene so there is no emotional moment in it like the scene in s4 when deku confronts all might about nighteye for the 1st time. The final issue is how after he gets saved by 1a, he goes completely to how he was before the war in s6 it's like it never happened the only thing that remains is his ptsd, he doesn't question what he did and how it was wrong, class 1a didn't teach him to stop being self destructive when that was what he was doing in the tartarus escapee, also when he was against nagant he went all out and nothing happened to his arms u can see it in ep 25, the progression went from roughly 5% to 10% to 15% to 25% to now 45% which makes it feel less earnt as it used to in previous seasons.

Remember guys this is my opinion don't take it to heart, i still enjoy mha i don't hate it i just highlighted some flaws i saw in it this season, this or season 4 is my favourite season
