Season 1 Reviews
Black Nerd Problems
William Young
Every single frame of animation in this show has so much care put into it.
Asian Movie Pulse
Panos Kotzathanasis
A great title that will satisfy those that enjoy equal portions of actions and parody, although the latter is obviously aimed at a more mature audience, since it demands for someone to think it through, in order to appreciate it
CBR
Irina Curovic
Whacky comedy abounds in this fantastic parody of the superhero and shonen genre.
New York Magazine/Vulture
Maya Phillips
Presents comically exaggerated villains, idiotic and incompetent heroes, and an accidentally powerful protagonist whose thriftiness and deadpan humor make him -- and this show -- truly one of a kind.
Den of Geek
Craig Elvy
Aside from the genius humour and excellent knack for eschewing convention however, One-Punch Man still delivers in the action and drama departments.
IGN Movies
Meghan Sullivan
It's a one-two punch of hard hitting action and comedy, and well worth checking out.

Eeven if you aren't a fan of anime or obscure superhero lore, One-Punch Man is a burst of fresh air that just might be the thing you didn't even know you were looking for.
Decider
Kayla Cobb
One Punch Man is about a boring and bored hero, and that characterization is what makes the series so great... Don't think just because our hero isn't entertained that this show isn't entertaining.
Common Sense Media
Melissa Camacho
Funny anime superhero series is violent, has some language.
Paste Magazine
Toussaint Egan
Even by the ridiculous standards of the superhero genre, One-Punch Man's ballpark craziness is a league all its own.
TV Equals
Americ Ngwije
It's very lighthearted, very funny.
