Plot: We have like 3 arcs to watch in this season of 25 episodes. Since shounens like these never provide enough in one episode, having more episodes in a season definitely helps. The show also does enough for the audience to not get bored. We have a sports festival arc consisting of 12 episodes that provide a lot of development for the uninteresting group of characters that were introduced in season 1 and makes them more acceptable for the upcoming episode. The focus on the 2nd arc is basically dragging simple concepts and exaggerating them. We have our typical psychotic antagonist who feels he kills people for just cause and the show will try to pretend that his ideology is actually something to at least think about. This arc has some fine action of course with some very good script writing that we get to see once in a while. The third arc is a less serious final exam arc that sets things up for the next season while doing what the show has managed to do throughout the season and tries to polish some of the concepts we've already introduced too.
Art and Animation: Animation for Boku no hero academia is pretty good. The fight sequences are done well too. This aspect of the show shouldn't be a problem to anyone.
Sound: Soundtrack of this show also does its job. Creating a nice warm tone and also telling the audience the events that are happening is important. They don't overuse it like a lot of shows do and that's one of the reasons it works.
Characters: Finally the biggest improvement of this season is the character development we get. The biggest example is Todoroki who gets plenty of psychological exposure in a nice amount of time. Midoriya keeps discovering certain aspects of his character as well as his fighting style. Iida gets much more development as well proving his character is not one dimensional. We also get to know more about Ochako who is likely to be one of the major plot players in upcoming seasons. The other side characters get a decent amount of time too. Bakugo is still a guy based on one characteristic of course. And I don't even know if they want him to be a better character or not. Perhaps that serves the purpose of the show later on. Therefore, the characters get a major boost this season which certainly plays a key role in the improvement we do see in season 2.
Impact: Other than those technical aspects Boku no Hero Academia keeps things simple. Its problems and solutions are unrealistic and yet people of all age groups can relate to the characteristics required to solve some of those problems. People can see a shell of themselves in the diverse group of characters. Considering the main target audience of the show, this is very important as it can also be helpful towards their growth during early teen days. The concept of what it means to be a hero which is pretty much the main concept of this show can play a big role in creating an anti-bullying mentality for the young generation. So basically this show maintains strong purpose while moving on with its plot elements.
Conclusion: Boku no Hero Academia isn't perfect yet. But the 2nd season did a remarkable job with visible improvements in most of the fundamental areas. It gives off a warm feeling, has a good pacing, often relatable basic character psychology everything makes this show worth watching.
