Grinzing through news, there was a headline on how Rogue One was an engineering film. So I skipped reading the review, and went directly to watching the film.
Big mistake. It turns out that the review was about engineering ethics, and not engineering. And the film was definitely not a reboot of the Lucas-verse with a working physics engine -- you know, for engineering to actually work.
Anyways... People saw it, and said stuff like:
In a civilization with hover technology a massive, super-slow, quadrupedal ground-based weapons platform makes no sense. Don't AT-AT me.
Seriously? That's the salient military criticism?
