An anime that revolves around psychoanalysis, particularly of the main character, Shinji Ikari. Ayanami Rei, whom Shinji developed romantic emotions toward at the beginning of the series, as well as Eva Unit 01, are later revealed to be, respectively, a clone(s) and the soul of Yui Ikari, Shinji's mom. LOLWTF.
But really, though, Neon Genesis Evangelion is an amazing, action-filled, complex, and thought-provoking series. The descriptions may seem stupid, but it's awesome.
