The TV Show has set a hefty standard of how good, dark and grotesque anime can ever get. Don't let an underwhelming Season Three and a Semi Decent Season Two deter you away from the series; this is the pinnacle of the anime genre.
Season 1 and 4 are rich with dark and horrific visuals, refusing to hide anything behind lame censorship. A coherent plotline that strongly comes together to deliver some really strong real world messages amid the slew of metaphors that asks us questions. Questions like - Why are people two layered? Why are people different at the surface and different within? Why and what do we hide within each other? This show is as much of a visual delight as it is a thought provoking masterpiece brought to you by a now renown studio.
The music, visuals and voice acting are strong and carry significant heft for anyone willing to peel the multi layered meaning and set up the ambience of this visual and auditory adventure. The direction is top draw and the show seems to be closely represented in the manga.
Side Note: Do not miss out on the opening songs of Season 1, 2 and 4 cause they were memorable, powerful and like most heavyweight anime opening sequences, have heavy references and symbolic meaning to the keen eye.
Sate your anime taste buds and experience the glory of unfiltered, the most edgy, dark and yet refreshing tale of a dystopian Tokyo where two divergent factions come to terms with each other. It is hard to not recommend someone to watch this.
