I'm really liking this OVA. The art and direction are good and you can see them experimenting with the editing. All the characters are nicely designed. Key herself is robotic but doesn't feel like a rigid cookie cutter anime character, she's stiff and aloof, a bit jerky and autistic, but still feels like a person. Story wise, there's a lot to digest here, migration from a rural village to the anonymous and noisy city, the struggle to find your place in the world, desire to be human, danger of weapons, conflict between what Key wants (to be a real girl and have friends) and what the corpos want.

One thing that really sticks out in a lot of anime are human-like relationships with non-human robots. Bots can be friends, they can have feelings that should be respected, they can be cared for. Compare that to American pop culture where robots are almost always associated with danger and fear or enslavement (e.g. Terminator, Ex Machina). I knew an anthropologist who said the difference is the influence of 'animism' in Japanese society? Whatever the reason, I really like this and I'm happy shows like this exist.
