The Greatest Showman will be in theaters in two days, but I cannot find any reviews of it online. Reviews usually come out days or weeks before a movie's release. They are often used by marketers to promote the film ("Best performances of the year!"). I don't think the movie was withheld from reviewers because it's bad, since it's been nominated for 3 Golden Globe awards including "Best Motion Picture - Musical or Comedy".
So why has The Greatest Showman been withheld from reviewers?
