I started watching this show with a bit of skepticism because I just couldn't imagine how they could introduce and develop characters, set the theme, and tackle a conflict in just six episodes, especially given how the episode are about 15 minutes long (except for the last one which is a little bit longer). This anime surprised me, however. Perhaps that's because it adapted a setting that is somewhat familiar if you've seen I, Robot or anything that involves humanoid robots (I, Robot is the best example I could think of. The similarity in the universes is uncanny).
If you've got an hour and a half to spare and you want an enjoyable and relaxing anime, watch this one. You won't regret it. It's not something that'll keep you on the edge of your seat, but it's something you'll enjoy and appreciate for what it is. I'd give it somewhere between 7 and 8.
