@Andrea_Lavander my opinion is complicated, as a mha fan fiction writer I love thinking about how the ending could have been. I think the longer ending and epilogue was good however Izuku not talking to his friends for eight years isn't something I agree with. Endeavor was the number two hero in a rougher Era and he had time to abuse his kids and wife so they had time to say hey Izuku thank you for saving us.
The "Iron Might" armor was good touch and while I would have preferred him to have a quirk I think it's better than somehow magically getting ofa back.
Overall not the worst ending but there are things I'd change but considering how much I've worked with the MHA world its not a bad ending to the full narrative
