This did what Neon Genesis Evangelion couldn't do in a TV series, a 2 movie recap a 2 movie ending, and a 4 part movie retelling. In a mere 5 minutes this masterpiece show how the entropy in our minds is an endless cycle much like the endless cycle of destruction and recreation that is life an death. First a man drinks from a mug in silence but as he repeats this day after day he is thrown into despair at the useless monotony of his life. this represents the human condition, we are born, we live, and finally we die. As he realizes this the music builds as he falls deeper into insanity. Eventually, he realizes the uselessness of it all and sips his coffee content, neither caring nor worrying about the world around him. He is enlighten.
I place this up there with other great works such as Eva, Serial Experiments Lain, and Cory in the House as one of the most cerebral and deep anime's of all time .
