Story 8/10
The story of One Punch Man, is arguable one of the weakest point of the anime. The story itself revolves around what I consider to be two main characters of Saitama who is average looking guy, with over the top strength and Genos the cyborg who wants to learn from Saitama. Now although the story is pretty solid and for me flows quite nicely from episode to episode, my main problem with it is that it feels like its holding back a bit and doesn't progress the story as much as other animes of similar length (12/13 episodes). Another slight downside to the story is due to the nature of Saitama's character you'll very quickly see that fights aren't the main focus point which is kinda of a shame and I'll explain later in the Art section why I feel that way. But despite that it allows the anime to focus more on actual characters which leads to some great comedy moments with the interaction of characters and some good character building and depth of Saitama and Genos.
Art 9/10
The art and animation is a great asset to the anime with its own nice style. It seems to me that the art style puts emphasis on the awesome fight scenes by making Saitama more detailed during the fights and being serious but giving him a simplistic feel outside of fights which helps comedy moments and when he doesn't understand what people are saying. Due to the fact that Saitama is quite basic in looks, it allows for other characters to look more bizarre in comparison and unique. Not just Genos with his cyborg looks and weaponary, but other characters (mainly other heroes) which creates a great aura about themselves. I should mention that the animation improves as the episodes go along, most notably in the opening which did have a side by side comparison on youtube of the original opening and then the same opening in later episodes which shows the improvements made, although its likely to be taken down by now. Now as I mentioned in the previous section of the review I said that it was a shame that they wasn't more fight scenes. This is because the fight scenes are one of the best qualities of this anime due to the flow of animation and art, and the fact that fighting scenes tend to be not that long, it makes me wanting for more which the story clearly doesn't really allow for.
Sound 8/10
ONE PPPPUUUNNNCCCCHHHHH! Is basically what is going to get stuck in your head when you hear the opening song for the anime. The opening song is what will get you hyped up into watching the anime. The song is amazing, it will make you feel like you are going to get pumped up into some great anime and action. In contrast the ending song is more relaxing and chilled. Which helps you to wind down after each episode. There isn't anything wrong with the sound but the reason I haven't given it more in terms of score is due to the fact the soundtrack within the anime itself doesn't particularly stand out to me, however I will say it doesn't really do anything wrong.
Characters 9/10
Basically the characters are great. From Saitama and Genos, to the random enemies, to the background characters and even the other heroes. The vast majority all have they own look, personality and chemistry between each other. Saitama and Genos have a great relationship with each other which makes the anime really enjoyable. The enemies have they own small backstories which they usually get across in a small time frame and don't outstay they welcome with pointless monologuing that some other animes are guilty of. My only complaint is that other heroes don't really get enough time to show off themselves but that is more likely due to the fact that the show is only 12 episodes long.
Enjoyment 10/10
There wasn't a single moment where I felt bored or that the episodes were dragging on too long. I couldn't wait for each episode and not only did I loved watching it, but it also caught the attention of my dad who ended up wanting to watch it with me even though he generally doesn't understand the appeal of anime or like anime in general. This shows to me that it can capture the interest of people who may not like anime or bring in people into the anime scene.
Overall 10/10
I will mention now that I only score anime from 6-10 because usually animes that I would rate 5 or lower don't catch my attention enough for me to watch longer then generally a couple of episodes before forgetting all about them. For animes I rate from 6-10, I rate on my own enjoyment of the anime, how off putting any potential plot holes, characters, story etc are, and if I feel I could re-watch the anime and still feel satisfied from watching it all again. For One Punch Man I feel like not only did I really enjoyed watching it, I will probably watch this anime over and over again within the coming years and any problems I have mentioned isn't enough that it will to put me off or to give it a lower score then a 10.
