I mean, you could totally make Home Alone II today as long as you set it pre-9/11, so I take this to mean "these movies that were set in the 'present day' could not be redone and set in the 'present day' of 2024."

You couldn't make Back to the Future because 21st century streets are no place for minors on skateboards.

You couldn't make American Beauty for a LOT of reasons (including prevalence of digital video, marijuana legalization, increased public awareness/concern about pedophilia, etc)

You couldn't make Clueless because shopping malls are dead (or at least nowhere near as cool as they used to be)

You couldn't make Trainspotting or Requiem for a Dream because heroin and cocaine are quaint drugs by 2020s standards

You couldn't make Paris is Burning because Harlem gentrified big time (I know this is a documentary but still)

You couldn't make The Matrix because no one would believe human batteries would be happy and content living in a simulation of 2024 (also no telephone booths)

I almost said The Truman Show because we basically live in that world already but fuck it, I wanna see a 2024 version where the producers have to keep desperately introducing crazier plot developments to try and compete for a TikTok-addicted audience unamused by "just another reality TV show", and constant set issues like cast members getting fired right and left for sneaking smartphones onto set.
