Just finished rereading and it is a great work it obviously isn't perfect and some elements were brought up and abandoned like the vampires and the loss of memory once the mission ended and you had taken serious damage, Oku probably didn't have a clear idea on the entire plot but he gets the themes across very plainly and the final chapters and ending are perfectly workable.
Which is why my head starts hurting at some of the comments you can find here with endless nitpicking of people that speedread the work or were reading only for the violence and tits, dumb comments for example about the CG (which does look bad and this terrible scan doesn't help) but the use of the CG has a clear purpose thematically if you pay attention and ask yourself why did the author decide to use CG at this exact moment when he could have drawn it since he doesn't lack any talent for it, or about how the first chapters were more violent and gorier (?????? maybe we read a different manga) or nitpicking about the mechanics of the ball or my favorite dumb comment when the translator complains about the orbit of the mothership between the earth and the moon as if the known strongest military alien force in space couldn't handle something like that.
Yes the talk with the superior being is sophomoric and you are supposed to get mad at it fuck the superior being and the final chapters are humanity's answer to it.
It's not a perfect work, was it rushed? possibly but the art doesn't lose any quality in the final chapters, and it is still one of the greatest manga ever made and fully recommended to read to anyone checking the comments, a solid 7-8/10.
