Twitter MG -RT: Are they really replacing Paget Brewster and AJ Cook? (via @ [Name Removed]) unsure and absolutely befuddled Deadline: UPDATES CBS' 'Criminal Minds' Cuts Female Cast The controversy over CBS’ decision not to pick up Criminal Minds co-star A.J. Cook for next season and to reduce the episode load of another female cast member, Paget Brewster, is not blowing over as fans’ campaign to reinstate them is growing. An online petition in their support has garnered 15,500 signatures, with the number rapidly growing. Among those who have signed it are Criminal Minds co-star Kirsten Vangsness, who is returning full-time next season, as well as Kevin Pollak and Paul Tompkins. Several other Criminal Minds cast members have voiced their opinion via Twitter. Brewster was the most blunt, taking an issue with the network’s description of its reasons for the casting changes as "creative." ""Creative Reasons" has been an Executive Bullshit excuse for DECADES,” she wrote. “It IS financial. AJ is a dreamboat. And yes, I am hurt, too.” Here is Thomas Gibson’s tweet: “To say we're all mystified and disappointed is an understatement...” Cook, who had been silent since I broke the story on Monday, sent out a thank-you Tweet today: “Your kind words and support have made me feel wanted and loved!” Meanwhile, fans are also emailing CBS executives and have called CBS Entertainment president Nina Tassler.
