Story-wise, it had a really good premise, but I feel like it wasn't as interesting as it could have been. I was also really disappointed with Deadman Wonderland itself. It's supposed to be this high security prison, but it didn't really feel all that scary. The prison breaks weren't really exciting either. Everyone just walked around whenever they felt like it.
Art: It does look pretty cool (Unsurprisingly. It was illustrated by Kazuma Kondou, who also illustrated Eureka Seven.), I really like the character designs. They all look unique and interesting. The animation isn't the best, though. It looked a little off at times.
Sound: I didn't find the sound all that impressive, but it wasn't bad either. It has a pretty good soundtrack. The only thing that annoyed me sound-wise was Ganta's voice actor.
Character: This was one of the biggest problems I had with the series. Ganta was pretty boring. The only time he did something interesting was in the last episode. Shiro was mildly interesting.
I really didn't care about anyone at all, though. Near the end there was a lot of flashbacking to make you feel bad for people right before they died. Nope. Didn't work.
Enjoyment: Some episodes were more enjoyable than others, but none of them were so boring that I paused to go do something else.
Overall, I think it was a decent series. It could've been a lot better than it was, but I still enjoyed it enough to watch the whole thing. If there's a second season, I'll probably watch that too.
