I don't even think I'd have the right to tear down anyone's list -- I actually think that even if an 22-year-old replied with a list of ten movies from 2016-2025 that he went to the cinema to see, and which he would be happy to recommend, that'd be enough for me!

I brought up this list: https://editorial.rottentomatoes.com/guide/essential-2000s-m... and scrolled through, and I think I saw at least half these movies either in the theater or as rentals, and most of the ones I saw I loved. Furthermore, I think at least a third are major contributors to the American cultural canon, both as being in the zeitgeist in the season of their initial release as well as being remembered going forward. For instance, people still today make references to "Mean Girls" or "The Dark Knight" or "Minority Report" that only fully make sense if you've seen those films or at least know they exist and their premises. And I think it would be pretty easy to make a list of 50-75 significant movies each from the 80s and 90s, but I'm focusing on ones during my adulthood to follow the spirit of your ask.

This is what I can't imagine finding ten of in the past decade. I'd be tempted to put "Barbie" on that list potentially, given how many memes I've seen using frames from it. Also, honestly, several Pixar films deserve to be on the list too, though I admit that I'm biased because they're some of the few that I've seen.
