"This is a movie about a guy that lives in a simulation. What if the world is a simulation?" is dumb stoner shit. "This is a movie about a guy that lives in a simulation. It is an allegory for this world, which is not *literally* a simulation but is artificial." is potentially an interesting thing to put in a movie. The late 90s had a lot of movies about that (Matrix, Fight Club) and you can tell the good shit from the copycats by whether they go with the weed teenager version or the "Boomers have ruined our society" version.
