Loved it, story made you actually use your brain while also showing how everything connects along the way ending wasn't some completely "feel good" solve all where everyone has a resolution, but instead it shows us how everything loops back around, sort of like AoT's timeline. A lot of the bad reviews come from the fact that this anime doesn't shy away from the real world and is not afraid to use more gruesome and dark plots instead of your regular "everyone is saved and nothing bad happens". Has a slow start but picks up the pace in a few episodes, and even though itmay feel a little rushed at the end I felt like it just added to the story as it showed how chaotic everything was.
