The premise for the show is fairly intriguing as the mysteries of the Abyss are slowly uncovered. Sure wish the pacing was better. The vast majority of the show is very slowly paced with little of note happening. It felt more like filler despite only being a short 13 episode series. The excitment is very fragmented, the last episode is by far the best one of the whole series. The earlier episodes did little to hold my attention, I was doozing out for the most part. I did not like the light hearted moments and definitely preferred when the series was more dark.
Art
Reminds me of Madoka Magica in terms of art style. It is a good juxtaposition to all the macrabre horror that happens later on in the series. Well animated as well. Animation and art is not a weakpoint.
Sound
I did not find the music to be anything super noteworthy.
Character
Not a strong point of the series. I am very indifferent to the two leads. Nothing about them really stood out for me. My favorite character, Nanachi did not show up until the tail end of the series. Her and Mitty's backstory was easily the best part of the series. Other than those two, I was very indifferent to the supporting cast.
Enjoyment
I heard great things about this series. I went in with a lot of expectations. I found the pacing to be a serious problem and the characters with a few excpetions were not doing it for me. Ultimately I am glad, I stuck around till the ending, but overall this was an average experience at best.
Overall
There were many moments when I lost interest in the show. I would go out of my way to recommend this anime.
