Story is bare bones. Meet Saitama, holy crap he's strong, episodic problem of the week and it gets punched hard. There is no epic story line or grand quest to save the world. Just an average guy being a superhero.
Art is amazing. Madhouse really went all out with this one. The fight scenes are glorious. The sheer impact and destruction of the attacks are the best I have ever seen. In stark contrast, the comedic scenes are so intentionally poorly drawn that it sucks the excitement away instantly. This is a very good thing. To be able to switch gears from awesome battles to a dopey moron instantly is extremely hard to pull off.
Music is very good as well. The opening is suitably epic for the strongest hero and the battle effects really bring it together. The ending is a bit underwhelming however. I'm almost convinced it was purposefully boring.
Characters are one dimensional. Saitama is a hero because he likes it. That's really it. There's not going to be any character growth. No gut-wrenching decisions or actions that shape his viewpoint. What you see is what you get. Minor characters see his actions and may start to reflect on how to improve themselves, but this is never highlighted and has no bearing on the show.
Enjoyment varies for every viewer. Saitama is going to win every fight, without a doubt. There's no trace of tension or anxiety in the show. Some people will find this boring. Others will watch for the comedy reactions of the background characters. This isn't a show that's going to appeal to everyone.
Overall its a good show. With a better story and stronger characters it could achieve greatness. But for now it stays an impressive visual work that deserves a chance.
