Director Brett Ratner says the film review site Rotten Tomatoes is damaging Hollywood.

"The worst thing that we have in today's movie culture is Rotten Tomatoes," he told an audience at the Sun Valley Film Festival.

"I think it's the destruction of our business."

Brett Ratner directed the Rush Hour franchise, and his company RatPac Entertainment co-financed Batman v Superman: Dawn of Justice.

He suggested that the way the site aggregates reviews is unfair.

Rotten Tomatoes pulls together scores from audiences and critics.

If more than 60% of the reviews are positive, it rates a film "fresh".

Any less than that and it's rated "rotten".

"The Rotten Tomatoes score was so low on Batman v Superman, I think it put a cloud over a movie that was incredibly successful," said the 47-year-old.

Batman v Superman performed well at the box office, making $868m (£695m) worldwide.

But Brett Ratner suggested it could have performed better if people had ignored the Rotten Tomatoes report.

It gave the film a "rotten" rating of 27%, although the audience score was much higher - 63%.

Jordan Horowitz, producer of the Oscar-winning La La Land, tweeted his support for the director.

But the Guardian's film critic, Peter Bradshaw, said it was a case of 'sour grapes'.

Rotten Tomatoes itself says the website should only be a jumping off point for fans.

"At Rotten Tomatoes, we completely agree that film criticism is valuable and important," Rotten Tomatoes spokesperson Jeff Voris told Entertainment Weekly.

"The Tomatometer score, which is the percentage of positive reviews published by professional critics, has become a useful decision-making tool for fans.

"But we believe it's just a starting point for them to begin discussing, debating and sharing their own opinions."
