This felt like a recipe where some key ingredient was missing. Seems like most of the steps had been followed, I could see that it was put together with care and skill, and yet... it just didn't catch me emotionally.
I did enjoy observing human beings through Klara's eyes. I felt that Klara was able to observe some blindsides of human relationships that we often fail to consciously consider. However, she was so alien in her own thoughts that it was difficult to draw anything interesting from her own observations. It was like "hey, isn't this interesting that human beings are like X", but there was no reflection beyond that. It was purposely stilted, leaving you to draw your own thoughts about X.
