One Punchman follows the daily life of the superhero Saitama, on his journey to find a worthy opponent. What makes him different compared to other superheroes? As the title already suggests, he's so overpowered that he can finish all his opponents with a single punch. "Sounds quite boring" is what I thought at first. It's for sure hard to make a story interesting where the protagonist is that overpowered. But the authors did such a great job with it. Its humour is what really makes it so good. saitama rarely gives a fuck, forgets the faces/names of his rivals, is kinda selfish and he doesn't take his work as a hero very seriously.

It's the combination of his overwhelming strength, his unimpressive attitude, his personality and his will to find a worthy opponent that makes this show so great.

Story:
There is not much to say except for that the story is pretty simple and easy to follow. It's nothing special, but it doesn't matter because it's not the story making it good. The only thing that's really bothering me is that most of the time it feels like the new stronger monster/monsters are just appearing out of nothing.

Art:
It's pretty good, but also not the best I've seen. But it's unique and fitting for sure.

Character:
The main characters are the ones who give life to the manga. Every character in Saitama's "squad" is unique and contributes to the story. They are the only ones who recognize Saitama real power and its the interplay between them that makes it so good.

All in all, I think this show really outstands because of it's incredibly good combination of comedy and action.
