One Punch Man is a cold refresh in the new era of anime, visually enchanting, funny at every moment and hilarious in the plot. From the first seconds of the first episode it's clear that the central idea about Saitama is make a new concept in the super-heroes stories, and let me tell you that it's very well achieved. Every time it's possible the series goes around the ludicrous bureaucracy that affects every organization, and make fun of that without leaving the battle between good and evil. Saitama, and almost all the other characters, have a real life; they work for living, they make their own shopping at the grocery, they bath, eat at restaurants, etc. but never forget their main responsibility: be part of the super-heroes society and fight against evil. This is a central point in the series, because it's about super-heroes and the protection of the world. One of the best things of the series is that anyone of the characters never leaves their natural innocence, and make you feel good about their feeling, even when their are trying to destroy something or annihilate the whole human race.

All this components make this series a very well developed story, and possibly a new classic.
