Just watched on the premiere. Just like in the last blockbusters "Godzilla vs Kong" and "The Tomorrow War", I had the impression that the white hats gave some notes to the screenwriters of "Black Widow". Lots of child trafficking references and also MK Ultra type of mind control project.
And the the bad guy at the end... No spoilers, just watch it (the movie is much better than the trailers). Also, the emotional core is a nuclear family, just like in "The Tomorrow War", even being a twisted one in the Marvel movie. Also, two traditional scenes after the ending (before and after the credits).
I was surprised about Tomorrow War, it had the global warming and polar bears losing their homes displaying on the TV in the high school but the family angle was surprising to me.
They did hit on the "less than 500K people alive" in the future and it was like there were some continuity issues or plot holes or something wrong with the story telling but it was OK.
