It looks like Warner Brothers just bought Flixter and Rotten Tomatoes. It seems strange to publicly out this buy to me. Being owned by a production company would make me a little less trusting of the site's credibility. It is mentioned that Flixter (Rotten Tomatoes) will be independently run, but ownership does have its privileges.
