Can someone recommend me an anime that stands by these conditions:
-Unknown/underrated, so no Death Note, Bleach, etc.
-Series if preferable, but films are okay too.
-Dark themed, with complex plot, twists, conspiracies etc.
-Not afraid to include blood, but no Happy Tree Friends; I'm not watching it for the gore but I don't want to watch Pokémon either.
-Can include mature themes but shouldn't focus on "plot", if I wanted that, I would watch a hentai.
-Fighting scenes are welcome, especially if epic, but no overpowered characters (Hellsing/DragonballZ) when they knock off a skyscraper with a blink.
-No childish animation style, sweat drops and red crosses appearing at the head, overreacting Jim-Carreyish, annoying pink haired screaming creatures which murder the perfect mood of a good murder mystery (7th episode of Darker than Black).
-No American clichés like the hero turning off the bomb at the last second, thus saving the world from the evil nazis and riding into the sunshine.
In other words: animes like Ergo Proxy and Gantz.
Sorry for being this specific but there has to be one like this. I just can't find it!
