I've been watching anime since I was a kid, so I've seen plenty of different genres, and different stories. To have people put this on a 9+ rating is extremely overestimated. If I was to say why there is so much hype about One Punch Man simply it's the animation and the music that goes along with the fight scenes. As purely an action anime I would definitely recommend it, however the story is rather mediocre.

Just a basic summary is you have an over powered hero who pretty much finishes every enemy with one punch, as the title says. I figured it would be pretty boring, but it was rather enjoyable at first, but eventually it lost its charm quickly. The fight scenes were still gorgeously animated but you already knew who was going to win the fight. It just adds such irrelevance to all the other characters, who lack character development pretty much completely.

A lot of the anime lately has been trashy, and although this was one of the better ones of the year, it by no means deserves all the praise it's garnering, which is mostly likely due to the appeal it also has to the western audiences. To have this rated higher than shows like Fullmetal Alchemist Brotherhood, Cowboy Bebop, Samurai Champloo, as well as other anime's that exceed in several areas that this anime has completely fell flat on just doesn't make sense. Honestly don't get caught up in all the buzz, if you just want to watch an action show with a bland plot, by all means, it's at least worth watching if you have the time, but there are a lot of better shows out there.
