The movie doesn't open until later this week, but it has received mixed reviews from critics. Negative reviews made some fans so angry that they flooded the site with profane comments and even threats against those reviewers.
Rotten Tomatoes says its staff couldn't keep up with the work needed to filter those angry comments, so it has simply suspended the comments section for now.
Matt Atchity, the site's editor-in-chief, said postings about "Dark Knight" reviews would likely be restored by the end of the week.
"The job of policing the comments became more than my staff could handle for that film, so we stopped the comments altogether," said Atchity. "It just got to be too much hate based on reactions to reviews of movies that people hadn't even seen."
"The Dark Knight Rises" is currently experiencing a glowing 84 percent "fresh" rating on RottenTomatoes.com, but the film has been deemed "rotten" by a few critics.
The final film in director Christopher Nolan's Batman trilogy opens Friday.
