I just saw this a couple days ago and agree it was a really good film. It was also, surprisingly, a fitting examination of the use of kamikazes during WWII. Way better than The Eternal Zero (which I reviewed upthread and, unlike Godzilla Minus One, was pretty much only an examination the use of kamikazes during WWII—and, unlike GMO seems to have been all for the use of kamikazes in the end. Pretty disgusting, actually.).
But Godzilla Minus One? Good movie. Heartfelt and earnest. People should see it.
