Boku no Hero Academia, now that I'm caught up to 101, I gotta say, the anime easily adapted the worst part of the manga. We only saw a whiny Deku who constantly breaks himself and has no confidence, we saw a bitchy Bakugou who didn't experience any of the moments of true character development that at least partly justify his attitude, and we got very, very little action for a series that, like many like it, experiences combat conflict after combat conflict.
Season two of the anime has a chance to be a lot better based on what comes after, but if they only adapt another 20 chapters, it's going to feel really disappointing and drawn out. At the least, the manga will stay a good read week by week.
