Privileged - It's really a shame that this charming dramedy did not survive past its first season. I personally thought it was a better show than 90210; it just received none of the buzz (though in reality the ratings weren't all that much worse; if you didn't know...every show on The CW gets terrible ratings!). A change in pace from most of the other CW fare, this show was more family-oriented (though still explored issues relevant to young people, from sibling rivalry to sex) and in my opinion, was really something special. All of the last-minute chatter that it might return midseason only made its ultimate cancellation sting more. 18 episodes (1 season) aired.
Reaper - Another CW fan favorite, Reaper already avoided the cancellation axe once after it was nearly canceled following the conclusion of its first season. However, it was rescued and brought back as a midseason replacement this Spring, though frankly, the network never put all that much effort into promoting it. Sadly, the series could not escape fate a second time. If it's any consolation, Tyler Labine will be back on TV next season in FOX's Sons of Tucson. 2 seasons aired.
Everybody Hates Chris and The Game - The CW had announced earlier this year that they were getting out of the comedy business entirely, so it isn't a surprise then that these 2 shows will not be returning in the Fall. Yet 2 more examples of decent shows that the network never really gave their full due. Neither were show on my regular viewing schedule; did they end satisfactorily? 4 seasons and 3 seasons aired, respectively.
Which CW cancellation angers you the most?
