The Internet Movie Database (IMDb) has implemented changes to the rating system for Disney's live-action remake of "The Little Mermaid" in response to "review bombing." 

Review bombing refers to the practice of flooding a production with negative reviews through the use of multiple accounts or bots. 

Despite receiving an overall positive average score of 7.0 on IMDb, "The Little Mermaid" has a significant number of 1-star ratings, accounting for over 39% of the total ratings.

In order to maintain the reliability of their rating system, IMDb has applied an alternate weighting calculation to counteract the unusual voting activity detected. 

IMDb has included a notice on the film's ratings page informing users about the adjustment made to the rating mechanism. 

The specific details of how IMDb calculates the weighted score are not extensively explained in their FAQ section. 

The film has been a target of racist criticism since the announcement of Halle Bailey, a Black actor, being cast as Ariel. 

Bailey shared her experience of receiving support from her family when facing the backlash, with her grandparents recounting their own encounters with discrimination. 

This is not the first time companies have taken measures to combat review bombing; Amazon previously introduced a 72-hour vetting period for user reviews of "The Lord of the Rings: The Rings of Power" after it faced racist backlash for casting people of color as Middle-earth residents.
