One Punch Man=Action/Humor.
Long reviews waste your time so here's one short paragraph.
Don't let the fact that this dude kills bad guys with one punch deter you. The developers knew that would get boring, so he is always accompanied by balanced heros to give you an action packed fix with dire circumstances. That being said, the characters in this anime are great! The heros he encounters all have unique personalities and abilities. It's also hilarious to see the different villains that emerge. One Punch Man tries to achieve ranks in a hero society of this story so he can become popular and recognized. But everyone thinks he is just a cheater even though he's the most powerful hero alive. The irony they build here will have you rolling in laughter. The art design is great. Everything is drawn with great detail and the fight scenes are epic in scale. The soundtrack isn't bad but it's not great. They throw in some distorted guitar and it sort of has is grungy garage band feel so it's okay. At the end of the day, One Punch Man isn't at the top of my list but it's definitely worth a watch.
Pros:
-Hilarious heroes and villains.
-Unique and humorous storyline.(it's not what you'd expect)
-Solid MC.
-Incredible action and art.
Cons:
-Unspectacular soundtrack.
