A.I.C.O. Tells the story of Japan being overrun with "matter", a sort of abstract material that destroys everything in it's path. The story is a bit generic but the pacing make's up for that. The biggest issue I had with this anime was the main character; Tachibana, Aiko. it's not that she lacks depth, it's the way she reacts to every situation. It's like she was made to be shocked at every turn. And it gets tiresome fast. The best aspect of the anime is the artwork. The elegant animations and fast pace of the series is what kept the two dimensional characters in check and made the series watchable. I did like the small details that made the world of A.I.C.O feel more authentic, e.g. the artificial suits that needed to be fed in order to function properly. I wish a little more thought was put into the world building of the series, it felt like I was watching a CW series with good visuals. There's nothing groundbreaking here, but it does make for a good popcorn anime.
