Deku is p*ssy. They literally repeated the bakugo dies storyline twice in quick succession
RIP Stain, the true GOAT of the series
All Might should have died against All for One in the war arc. Thus fully unlocking One for All power in Deku. They pump faked with his spirit outline being present way too much just to throw that away
Deku is a bytch. The world on the line, they told him to go for the kill. Here his lame ass go "imma save Shiggy inner child

" it backfired
Then they abandon the entire love plot with Ochako and Deku. Which is literally a driving force in the story

. The amount of time wasted on Toga

. The other school only sending 3 Jr license students to the war Frontline despite the stakes of the battle
The ending was such a cop out.
