The review aggregation site Rotten Tomatoes said that it had suspended user comments on reviews of the film, directed by Christopher Nolan, after readers reacted angrily to two negative write-ups and made threatening and derogatory remarks about the critics who wrote them.

On Monday, Rotten Tomatoes posted and linked to a negative review of “The Dark Knight Rises” by Marshall Fine at his Web site hollywoodandfine.com. That generated a wave of irate reactions from “Dark Knight” fans – many of whom have not yet seen the movie, which opens on Friday – and an overwhelming influx of traffic to Mr. Fine’s site.
