Deadman's Wonderland
Don't know if this one's highly acclaimed or not but my friends spoke highly of it, so here it goes.
Dropped it on my third episode. I really can't stand a world where the common folks living in it seem completely and totally retarded.
First a lawyer somehow manages to convince a jury that a (13, 14? can't quite remember) kid blew up an entire classroom without explosives, while being in the middle of ground zero, with zero motive, zero knowledge of bomb making and absolute and complete confusion stampered across his face (in reality some flying uberdude called Wretched Egg - I shit you not).
Then he gets sent to a prison without parole that doubles as an amusement park. The prisoners are used in death games and controlled through a collar that poisons them daily, and needs "candy" (literal wrapped candy with an antitoxin or some shit) to survive. Could be an exploration of a dark, dystopian society? Nope, no one on the outside knows this is happening, and they think the death games are ALL STAGED. Really??? You think prisoners would run around pretending to be stabbed by a giant spike (just one example) for the amusement of a bunch of school boys/girls?
He also discovers he has blood powers that allow him to create weapons out of his blood and that's why he was framed to go to the jail, because there's some ancient bloodfighting tradition or whatever, didn't get too far.
Honestly, all this grinded my gears, but I could support it. I've seen more retarded things in animes.
BUT THEN COMES SHIRO. THAT STUPID LITTLE SHIT.
Shiro is a flying naked (somewhat) girl that just perfectly exemplifies everything wrong with the Genki Girl bullshit anime writers like to rub on the audience's face. Nothing she does has any foot in reality, no one reacts strongly to her behavior or presence, and her voice is so ear-rupturing annoying I'd rather hear a stereotypical drama protagonist ***** and moan about how bad their sheltered, confortable lives are than watching another second of Shiro. It was the final nail in the coffin of an anime that I can't recommend to anyone I give even the slightest hint of a shit about.
