One thing that I think makes this movie so special
is it reminds us of what America is supposed to be, choosing good over evil, the light over the darkness, standing up to the villains on the world stage.
Unfortunately, over the last few decades, America has strayed from that path. Most of our leaders have been bought off by billionaire plutocrats that care nothing about the fate of our nation, and that has led to America becoming one of the greatest villains on the world stage. We have started needless wars in multiple nations on fabricated evidence (e.g. Irag, Syria), and the U.S. didn't even give a reason for decimating Libya, which was one of the most peaceful and prosperous nation in the Arab world before America and its cronies smashed them, turning them into a wasteland run by barbarian slave traders.

Now the U.S. is pretty much forcing Ukraine to keep fighting Russia. Why? Because the billionaire plutocrats that want to rule the world want it. Ukraine negotiating peace would throw a big wrench into their palns.
Top Gun Maverick reminds us what the United States is supposed to be about, freedom for all people, opposing the boot of globalist tyrants that wants to make slaves of all of us. It reminds us of what America is supposed to be all about, and that is why it resonates.
