Anyone who saw the promo poster and still watched the anime, has no business complaining about fanservice in this anime.
I'm glad to have had different historical problems with this anime than everyone else. Notably
samurai chicks slicing up B-29s
It wasn't until I got it through my head that well, they lost a few of those didn't they, no matter the cause? But then I digressed into a what are they thinking mode, when I thought about analyzing how they thought women from 70 years ago, could have been in anyway in some form of military combat roles. Didn't they watch Zipang? lol
But once I stopped analyzing it for accuracy, and whatnot, I could start to enjoy the design of the anime and the animation. I didn't get so upset over the ink blots as some here. I thought it was better than "Oni brand" censor strips. Or a few other types I have seen, to get a show on air.
Overall I liked this show. We'll just have to see if I can relax and enjoy the potporri of of mixed eras or not.
