Deadman Wonderland
While the cult following behind Deadman Wonderland was happy enough to see it get an anime adaptation at all, the series’ source material is more than worthy of getting a full adaptation remake.
Following the events covered in the current anime adaptation, the world and its characters are explored in far more depth.
Who each prisoner is, the meaning behind their powers and their interactions with one another are all fleshed out beautifully, all while over-the-top battles full of blood and gore are put on full display.
That’s to say nothing of the main plot. Secrets like the cause of Shiro’s madness, her past with Ganta and so much more are revealed in earnest, giving meaning and depth to all that came before it.
To that end, a regularly released full adaptation remake in line with 2011’s Hunter X Hunter could be a sure-fire success. It may take a bit of time to get the ball rolling, but its darker themes, story and art style would no doubt find an audience before long.
