This anime certainly is a strange one for me. After about six episodes I decided to binge it because I found it boring but my completionist spirit wouldn't allow me to drop it. After 12, I realized it was a full series and decided to soldier on. At this point I was hovering around a 5 or 6/10. The story telling seemed bland and uninspired, the action scenes seemed well done but were few and far between. The constant exposition and narration I found very annoying and detracting from what became a very enjoyable post-apocalyptic tale. By episode 20I was considering bumping up to 7 because everything felt like it was hitting in the sweet spot at that point. I playfully mused that I would bump it to an 8 if it knocked the ending out of the park and lo and behold, it totally did. Don't often see that: A relatively disappointing and mediocre anime turning the tables in the last arc. Disclaimer, I feel personally connected to the overall message of the show (SPOILER): losing faith in humanity yet still being in awe of life. And this was extremely well presented in the finale of the show. The first half of the series only vaguely represents this and honestly seems pretty mundane and poorly executed (though there are exceptions, the humor hits pretty good at times, the animation is pretty good, and the action scenes are often great, though not enough to make the show interesting until the second half.) This show really brought its A game in the final stretch, enough that I felt compelled to write a review of it. If anime is your life support in a disappointing reality brought on by human shortcomings as it is for me, I recommend this show. The dreary first half keeps me from rating this show higher than an 8 but dang it finished like it had a purpose, in a way that few shows do.
