Unforgettable was cancelled by CBS after its first season aired last year. In fact, the ratings of this series, which airs every Thursday at 10 pm, are quite good, attracting an average of 12.1 million viewers per episode. But CBS did not give up on the red-haired beauty detective with hyperthymesia, Carrie Wells, and also renewed the second season for 13 episodes, which is scheduled to be re-aired in the summer of 2013. Unforgettable will return to the screen for the second season in the summer of 2013. It is said that this season will be different from the first season. According to a report on the TVLine website, the cast of the show is undergoing a major change. However, the heroine Poppy Montgomery has signed on to continue to star in this reborn series, and Dylan Walsh and Jane Curtin, who work well with her in the series, will also meet the audience again. The other three detectives, Michael Gaston, Kevin Rankin and Daya Vaidya, bid farewell to the show, which means that this New York Police Department team needs fresh blood.
