General audiences use Metacritic all the time. It gets noted all the time for video games, it's not an obscure website. More importantly, it tracks how the critics actually feel about the movie other than good/bad. Fall Guy did not have the kind of "divisive" response Joker did that actually propelled the movie, nor did it have the near-universal praise of something like Oppenheimer or Minus One. It was "this is a good action movie" not "this is an absolute world beater and savior of movies".
