Our protagonist, Saitama, is a self-described "guy who's a hero just for fun". As the story goes on, various characters are introduced who seem to take this hero business much more seriously than Saitama, who really doesn't give a shit. While everyone is freaking out and obsessing over hero related things, Saitama is pretty nonchalant about the whole thing. The buildup to various conflicts is really entertaining, and you will often find yourself in anticipation for the usually laid back Saitama to arrive. There is also more behind the scenes that isn't clear yet, paving the way for as of yet unannounced sequel. The story arc does feel a little too short, but that doesn't take away from the story. The premise of the show itself is much more entertaining in action.
The art and sound are quite well done, it's not jaw dropping but is nice to look at and listen to. The fight scenes are the best part of it all and look great.
Many characters are introduced and none of them feel particularly corny. Some have immeasurable power and others are your Average Joe trying to be a hero. All of them were entertaining, though all but the main characters and some of the villains have a deep backstory, which some other heroes could use. They are strong characters but it didn't really deliver on hearing about some of them as much as we would like to.
That said, they help build and drive the world around Saitama. While he may not truly care about being a hero, there are plenty of others who do. This contrast is the driving force of the plot. It can easily turn from a bit intense to a bit more lighthearted and humorous, though it never feels dark or all that serious, largely due to Saitama.
You will likely not find yourself worrying about that too much about character development while watching the anime. It is gripping and you may find yourself binge watching it. With so little time we didn't have much of a chance to see many characters grow as people very much - except for Genos, Saitama's disciple - although they are very entertaining and already have interesting personalities.
You may enjoy this if you like action and a cast of characters that do a good job of supporting the plot and the main characters without overshadowing them or being little more than background noise, as well as lots of poking fun at silly tropes, and a mostly easygoing and fairly straightforward story.
Final verdict: 9/10
