First of all, I have to be honest with myself.
This arc was amazing, nobody can deny this!
We had a lot of good moments, development of characters (i was fall with Katsuki and Aizawa again), revelations (cofcofDabicof), deaths, the cute Touya has broken the heroes society and the Shoto's mentally healthy, the people have lost the hope and are filled with doubts. Now, nobody knows what is the future of whom once time was named "heroes".
On top of all that: we had the big return of OFA (actually he never left xD) I know a lot of people didn't like that Shigaraki was manipulated by OFA and he dies but, remember OFA was always the main villain.
Anyhow, I can't with the fact that Horikoshi refuses to kill an important hero when he "did", something inside of him repent and show us that is never was died :/.
For last: I was pretty happy to see Mirio bebé in action again, I had missed him so much. Dynamight you rock. And Deku, geez you have grown up!!
