Deadman Wonderland isn't your typical seinen. It has quite its unique distinctions, and is a worthwhile read all right.

Story - 8 :
10 years after a great earthquake that ravaged most of Tokyo, Ganta Igarashi is the only witness of the murder of his entire classroom by a person clad entirely in red. As such, he is framed for the crime and sent in death row, in a prison called Deadman Wonderland that serves as an attraction park ran by the prisoners. His encounter with an albino girl named Shiro will urge him to live on, and discover the mysteries of the prison and of the Red Man.

Yeah, this is a pretty basic premise, isn't it ? But while the initial starting point for the story might hint at a survival manga in a crazy environment, the scenario will quickly focus on battle by introducing special powers and factions inside the prison (no telling there, go read it :p)

Art - 9 :
The art is, truly, splendid. Each character has many little details and quirks, and the style of the artist truly suits the madness of the story. Some double pages are seriously worth the read.

Character - 10 :
And this is where, ladies and gentlemen, Deadman Wonderland really shines.
Very quickly, you'll see that every character, besides the hero, is crazy. Each one has something tied to his past that shapes his attitude in the world of Deadman Wonderland, that you understand when the characters are developed. Ganta is the only sane person in the prison, striving to survive without becoming mad. As such, his character development is exemplary. Shiro is a weird girl, but she wants no matter what to be Ganta's friend, and when they get separated by the ordeals they live,Shiro's pain is heartwrenching.

Enjoyment : 10

I loved this manga, from start to finish. The combat scenes, the powers, the characters, the end of the story... Everything.

Overall : 9
Yes, only 9, because no manga is perfect. (Besides 20th Century Boys, but here lies not the debate :p). But, as you read, Deadman Wonderland is an excellent manga, and if you like gory seinen story (Gantz, Mirai Nikki, Elfen Lied...), you'll like this one.

Plus, it's completed now. You've got no excuses, go read it all at once !
