Deadman Wonderland has to be one of the most unique and interesting manga I've ever read.

Story (9/10)
-
The story is very,very interesting. The way they made it so each chapter explains it little by little makes it much more worth reading instead of boring fillers. The story in itself was unique,the explanation and experiments.

Art (8/10)
-
The art is great,the expressions drawn very lively. Simply by looking at their expression,you can practically feel their own emotions wash over you. From smiles to tears,from joy to pain,everything was expressed well. The details of all the gore were clean and crisp,not too messy,but detailed and well drawn out enough to give you the sense of how good it is.

Character (10/10)
-
The characters were outstanding,they were amazing. Many of them had special traits,their own particular ups and downs,their own strengths and faults. Even Ganta,the main "hero"-type character,has his own strong weaknesses. And each and every person had their own personality,and it had individuality. There was no "Oh,she's similar to..." and "Wow,it's just like..." in there. No. Everyone in DW are all unique.
When a character is proven cruel,it sticks true to the point and doesn't stray. And you can imagine how great all this individuality is,with the large variety of people who appear in there. By far,one of the most interesting characters I've ever seen.
Their backstories were all unique,and saddening.

Enjoyment (8/10)
-
This series was very enjoyable. I would sit still for hours reading it,to the point my feet got numb. The sheer mix of story,art and character blew me away. And that is without saying all the twists,turns and surprises. Some parts can be predictable,but that is rare,seeing as DW always has a surprise around every corner,and I cannot stress out enough how many corners there are.
The plot development was beautiful,the character developments entertaining. Their powers and skills and how they used it was wonderful,and the backstories were honestly saddening.
It seems in each chapter,a little more about Deadman Wonderland is explained. They make it like a jigsaw,with at first many scattered pieces and you're wondering how it all got there and why. Chapter by chapter the story is given in bits and pieces,and it's the type of manga that makes you piece all the pieces back together on your own.

Overall (9/10)
-
Overall,I'd say I wouldn't mind re-reading this at least three to five times. It's entertaining,the cast as well,and it's definitely worth your while.
