‘Little Mermaid’ negative reviews compel IMDb to change rating system

They’re making waves.

The Internet Movie Database has changed its rating system for the newly-released live-action “Little Mermaid” amid “unusual voting activity.”

The Halle Bailey-led film has a 7/10 rating on the site. But a few crabby users — also known as review bombers — are allegedly giving the Disney flick negative scores for no good reason.

“Our 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,” a note on the US, Canadian, U.K., Brazilian, and Mexican “Little Mermaid” pages reads.

IMDb continues on its FAQ page: “Although we accept and consider all votes received by users, not all votes have the same impact (or ‘weight’) on the final rating.”

“When unusual voting activity is detected, an alternate weighting calculation may be applied in order to preserve the reliability of our system,” the statement reads.

IMDb further stated it won’t disclose how the new method will generate the rating to ensure it “remains effective.”

The Post has contacted IMDb reps for comment.

While the exact reason for “The Little Mermaid” backlash is unclear, the movie was previously slammed by racists upset that a black woman is playing Ariel.

And some Disney fans may not be hip to live-action remakes of classic mouse house cartoons.

Other controversies surrounding the film include fans’ criticism that Flounder looks like he was “put on Ozempic,” and Disney not hiring a queer makeup artist to do Melissa McCarthy’s Ursula glam.

Nevertheless, “The Little Mermaid” is tops at the box office, grossing $209 million worldwide since opening Friday, according to IMDB’s Box Office Mojo.
