J. Kim Murphy The Internet Movie Database (IMDb) has made changes to its rating system for Disney’s live-action remake of “The Little Mermaid” after the new release became the latest target for “review bombing” — a practice in which a production is flooded with negative reviews by users who wield multiple accounts or employ bots to create new ones. Since its release, “The Little Mermaid” has garnered 41,000 user ratings on IMDb. While the film has earned a positive 7.0 (weighted) average score, more than 39% of the ratings are 1 star, the lowest possible option. IMDb has placed a notice on the film’s ratings page, writing that the site’s “rating mechanism has detected unusual voting activity on this title. To preserve the reliability of our rating system, an alternate weighting calculation has been applied.” This message has been employed before by IMDb in the cast of other atypical user score patterns.
