This plot is decent, but it feels like it was stretched out too much. The start was also sub-optimal, as it was unclear what the story was even about until almost half the show had passed. The second half was an improvement, primarily because I actually knew what was happening. The series also has some decent slice of life episodes.
As for the ending, it was actually pretty good, the only disappointment being that the epilogue felt really rushed, and a few things were left unclear, presumably to promote the game.
The audio is amazing in most cases, with the op's and ed'd being some of my favorites of the season. Character design, while unusual, was also pretty nice, and their personalities were also fleshed out, and weren't 2 dimensional.
But the excessively slow start of the show is why I cant give it more than 6 stars, since it will probably kill most people's desire to continue to watch the show.
