Though not particularly deep, the show has its moments and does a brilliant job of alleviating the constipated drudgery commonly found in action anime. Saitama, the "One Punch Man" is a hero so strong that he kills things in one punch which makes for some funny situations. For instance, since he kills things so fast, no one ever actually sees him killing things which keeps him from climbing up the ladder in the hero business.

Though we have seen powerful and bored characters in the past, it is usually the signature of a anti-hero or a antagonist but in this case, its the source of comedy to the show. He is so absurdity strong, that he get depressed when something dies in 1 hit. All he wants is some credit for his work and someone that can fight back and pose a challenge and that is basically the what the show is about.

One Punch Man pokes fun of other anime like DBZ and all the plethora of fighting anime who have useless dialog and endless "power ups" to fill in screen time as if it were fun to watch. In this one, when people monologue, its over the top and meant to be funny. When people power up or transform or whatever, it makes no difference and they get crushed the same as anyone else, which is equally funny. The show moves faster than most fighting anime which helps it stay fun to watch though season 2 felt much slower than season 1.

In a lot of ways, Saitama is the comical version of Superman. The point of the character is not the struggle against evil but rather the struggle to stay good in a world full of violence, bigots, greed mongers, posers and dimwits. Its a good show and definitely worth a look if you like action anime or just comedy.
