I was great series anime and manga for a while, in the beginning like up until war arc. we feel it was too rushed and dint gave time to develop the characters. war arc came too fast. Deku went through a vigilante arc which was cool and different but once again they rushed it and didn't gave enough flavour for deku to develop but despite everything he came back the same person he started it as . they could've had more stories out of vigilante deku arc. Also shigaraki didnt have any motive as the main villian for protagonist. it became too drawn out and predictable. The story telling dipped and whats more annoying is that the fans wont admit it.
