This is the first review I wrote for one of the most hyped anime series ever! And boy, the hype was worth it. This anime was a blast. Oh, and also: THERE MIGHT BE SPOILERS.
Story/Enjoyment: 8.5/10
I couldn't really see a plot in this anime, which was why I combined the score of the story and the enjoyment. This absolutely had no story whatsoever, BUT... it doesn't change the fact that this is a parody. There was no intention for a story. This was just a sit-back-and-relax type of series where you don't need to think and take it seriously; and I don't mind that; because I freakin' LAUGHED MY ARSE OFF HERE! This was hilarious. The battle scenes were very intense and exciting to see as well!
Art: 9/10
Well, what to expect from Madhouse Studios. The animation... Two Words: Madhouse Level...
Extra words: Which is GODDAMN AWESOME!
Sound: 9/10
The sound FX were like the extra sprinkles added onto a CAKE! Yep, not a turd. The sound effects had made me fall off my chair. The final battle scene was one of the MOST INTENSE AND EXCITING SCENES I'VE EVER SEEN!
Character: 10/10
I loved how Saitama had went through each of the "arcs" and finally take on one of the most powerful enemies he's taken on. First of all, it was like eating a piece of sultana. Then as the series progressed, the enemies had become harder to beat until at the final battle, he couldn't beat the enemy within ONE PUNCH.
Overall: 9/10
That was worth the 6 hours of me watching this. I'm also excited for the second season airing in 2017!
