I give it a 5 star because of its animation and mystery style story telling but I feel upset watching this anime. I know its fiction. But imagine your living this kind of dystopian world where robots have feelings and rights. What a sham. Crying over a piece of metal that have feelings? Has this world gone mad. People who created this machines is at fault. We are on the brink of DEVELOPING A FULLY AUTONOMOUS AI. I hope this kind of world will not come to the real world.
