Anybody find the ending kind of weird and unsatisfied? I feel like the other half just lost the initial intention of the story. And what annoyed me the most is that what Taro's sister said at the school gate stay unrevealed (Or I just missed the revealing part? If so please do enlight me)

How much of the critical plot will I lose if I will watch just the movie instead of series?

Anybody know the soundtrack/ost that plays while Rappa takes on Fatgum and kirishima in My hero Academia? This is from Boku no Hero Academia Season 4 Episode 9
