I found the plot to be quite bland and predictable. The characters are incredibly unidimensional with their essence of existence being one or two memories from the past and a single objective that stems from them. The protaganist is an amnesiac who knows nothing about the surrounding world. Everyday he seems to meet someone new who gives him a new outlook on life or a glimpse into the past. The protagonist and a few other characters wander the wasteland and somehow keep stumbling across each other for no apparent reason. Everyone's obsession with the ruin is understandable but somewhat annoying. All in all the world building is poor and neither the present nor the past make too much sense.
Something which surprised me was the anime's utter lack of ability to evoke any emotion. I was just apathetic to it throughout the watch.
'For whom do the flowers bloom' was for me the best episode, it pondered upon an interesting concept namely the absurdity of natural phenomena. The final few episodes too had interesting takes on the paradoxes of life and death. Another good episode featured the psychoanalysis of a character and contemplated the loss of meaning in life.
The symbolism however, is incredibly hollow and banal. The rhetorical narrative is repulsive at times.
And the plot twists are incredibly unrealistic. I don't think it has any profound thing to say. It's just a hollow, pretentious mess.
