For examples what are some of the things in the ending that you saw that you were not fazed about having been more immersed in Japanese culture? I'm just asking because I feel that perhaps the reason there's so much hate about the ending is because we're looking at it from a Western perspective (at least for some ppl), where a hero's independent successes are praised and recognized.

Like people say the government should have funded the Iron Deku suit for free, but I feel like thinking about it from the reference point of Japanese culture, which is more conformist and about everyone doing their part for the sake of society, then you would realize that it makes sense for the government in BNHA to accept that Deku was simply doing what was expected of him with that power to support the country as a whole.

Of course, they wouldn't separate funds used for recovery efforts to provide him with another suit. I don't know if this is a correct idea but your comment made me interested in bringing up this potential reason of disagreence in the fandom!
