The JOKE here in OPM is one of those jokes where it leaves you amazed for a long time but it cannot be repeated. You make that joke and you finish it there. It is extremely funny and everybody likes it crazy but yuo can't keep repeating it. The magic of that joke has a cooldown. Once in a blue moon we get Tatsuya, Alucard, Raizel but that's all. You remember that generic shounen MC gif, yeah that's what I am talking about. The craving for OP heroes is real. THE ULTIMATE STRONGEST HERO, we were waiting for that. However what happens once we get it? It doesn't get better than that so it starts to fade after a time. No matter how good the joke is, you can't keep telling it and that's the problem with OPM. Now do I want Saitama to be beaten? Absolutely not because that would defeat the whole purpose so that's also not an option. Then why the hell did I gave a 9 to that show.
1- Saitama is OP and no matter how repetitive it is, I would rather have a repetitively OP hero instead of a repetitively lame hero we see in 99% of shounen genre.
2- Side characters. In this case we are only interested in Genos. The way he is designed actually shows that even the creators of this show was aware of the repetition so they added Genos, the hero we know so well from any other shounen. He is the exact opposite of Saitama and having both of them actually does a damn good job at showing the contrast between the two.
Genos is flashy as fck, from his hair color, hair design, eyes, his body to his combat style and even his mentality. It screams the word flashy. Saitama on the other hand is made to be the most simple character. Genos lives that Ichigo syndrome being a generic shounen hero he is, and he gets stronger overtime and every battle he fights is always on even grounds, back and forth epic combats. Saitama on contrary is ONE PUNCH. Genos have that tragic past like every shounen hero while Saitama is just a dude who become a hero as a hobby. They fill the void Saitama leaves behind with Genos. Genos provides standart drama and eyecandy to the show and Saitama provides the epic feeling you rarely get. And please note that, epic things are epic because other things are ordinary. If all we saw was epic, it would get boring and thus NOT EPIC. And that's why I gave it a 9. They somewhat keep the magic alive and doesn't overuse the EPIC feeling. Also anytime a character realizes Saitama's strength, I am watching for that reaction. So there is tons of material too.
