The details of the black & white still shots for the OP is absolutely stunning. The OP may not be fancy but I think it adds a documentary type vibe to the series. It sort of reminded me a bit of Flag, impact wise, at least.
Spoiler for episode 1:
Nice proper episode which introduced a day in the life of a ordinary Japanese family. Small things like purikura of Mirai's friends and the fake(?) Ribon Mascot Comics looking manga on her bed made me feel like I was in Japan. The animated tour of Odaiba - Rainbow Bridge, Miraikan, replica of Statue of Liberty - was a treat.
Mirai obviously has a bit of a problem with human interaction. Well, she got her wish at the end of the episode when she wished that everything should just fall apart.
I wonder how that motorcycle lady with some sort of Tiger logo will come into play. I also wonder if we will get to see those Tachikoma rescue robots in action in the near future.
If they are making this realistic as possible, I can only expect nothing but chaos. Hopefully, a good chaos.
