Anime I should go back and watch
While my full-blown interest in anime waned a long time ago, I will always have a soft spot for Paranoia Agent, Paprika, and Serial Experiments Lain. As well as the space western trifecta of Cowboy Bebop, Trigun, and Outlaw Star.
And I can't forget Kaiba. My favorite show that never made it across the Pacific. A dark and twisted romance story/social statement with the saccharin aesthetic of Osamu Tezuka.
