Review bombing is a strange aspect of the state of cinema in the Internet age. The term refers specifically to the phenomenon of users posting negative reviews of a film in order to lower its average rating. Review bombers often haven’t seen the film that they’re negatively reviewing, or are reacting to an aspect of the film unrelated to that film’s actual content. For example, racists might review bomb The Little Mermaid live action adaptation because they don’t like that a Black actor was cast as Ariel.
