@Porthos The same happened with Brie Larson's Unicorn Store, it was targeted by some incels, who weren't happy with her and it was the men that voted with too many 1 stars without even the movie yet coming out and of course there were some counter 10s. Imdb should do the same thing that RT did, with not being able to vote on a movie before it has been released, and they should really separate the voters into verified and unverified.
The name of the lead star in Dora should give you an idea of who is downvoting/review bombing this movie.
