AICO was such a poorly done anime.
Classic example of a beautifully animated anime slapped onto a poor plot.
All of the characters were all annoying.
The story was thrown at the audience way too fast with all of this information & was jump-started extremely randomly.
It just sucked. It pulled a lot of elements from popular anime (you will DEFINITELY see a lot of Attack on Titan in this) which showed how creative the creators were.
A lot of anime now-a-days have turned into a cutesy copying cesspool of junk & this is one of them.
Animation can NOT save a bad plot.
I couldn't even watch this as background noise, it was so so bad.
