Watched it on the high seas due to peer pressure. Wanted to see all the others first but now I'll have to do it in reverse.
The war clearly gives off Israel/Palestine vibes; the only Russian/Ukraine likeness is superficial (old dictator, Russian-esque language). You have a horde of brown people being run down by a military force with superior technology, the Boravians have tanks and other vehicles while their opponents don't. I don't think you could have a stronger analogue for Gaza unless you're willing to show they've got hospital-hijacking terrorists in their ranks. As someone said earlier, they grill the shit out of Superman for interfering with foreign nations yet the Justice Gang gets to do whatever, even directly assassinate one side's leader. I have no faith there will be consequences to them for making this decision.
The movie has a very strange delivery on disasters. All the people sit around and take pictures and do whatever while a big fight is happening, and when the big disaster occurs there is no way everyone survived that, much less evacuated in time. It's a little cult-like since everyone seemingly has no self-preservation, and a little naive in that people would most certainly die if they're not trying to get in an underground bunker or anything. It's a miss that Gunn, in his obsession with cramming in extra characters, did not bother to add in metahumans assisting their escape near the end.
