That might have slipped your mind, even given your incredible intelligence and knowledge—which you made a point of showing off here—but it’s just an anime. It’s not real life, lol
And speaking less sarcastically, all of Inagaki’s work is full of exaggerations. You can’t expect everything to be portrayed in a way that’s 100% true to life
"but even as anime only I can see that the fight was rushed, I don't know by how much or maybe even how much was cut, but I could feel that this probably wasn't all there is to this and judging by how op worded it I think this feeling got confirmed."
Why are you worrying about something for which you have no hard evidence at all? Forget about those hipsters manga readers and enjoy the show. Just remembering that Shinra x Sho was amazing and and resolved in a single episode as well
The fanservice in the last minute with all the 'quirk armor' stuff was disgusting. Despite that, and the issues long debated in all the series, the message was really good, with a lot of entertainment, especially at the beginning and the end of the journey.
There were very few shounen who ended with such dignity...
The ending was mature and very fitting for a hero journey's perspective. With stakes, sacrifices, and the beautiful message that in the end, the power scope in 'heroism' doesn't really matter. Midoriya was a true hero trying to grab the kid as a teacher at the same intensity when he delivered the final blow in his last fight.
It is you that needs to grow up, actually lol
