HBO's drama John From Cincinnati may have wrapped its first season last night but that hasn't stopped the pay cabler from enacting a swift blow to the series. That's right, folks. John From Cincinnati is dead. Just don't expect the convoluted metaphysical surfing drama to rise from the dead any time soon. HBO has confirmed that it has canceled the series, which failed to connect with critics and viewers alike. In the meantime, the pay cabler hasn't yet decided whether it will renew comedy Flight of the Conchords for a second season. On that front, I have to beg for some mercy and only hope that HBO sees the merit of keeping the quirky comedy around for a while longer. Pretty please?
