ABC has pulled the plug on one of its soapiest dramas; the network has officially cancelled Revenge after four seasons. We can't help thinking this has to do with the unfortunate demise of one of the central characters this week (be watching Monday night!). The show's first season was so promising, but the following seasons undoubtedly lacked the same originality and compelling plotlines, leading to poor ratings. The series finale will air in the US on May 10. Sorry, fans!
