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.

In the meantime, the pay cabler hasn't yet decided whether it will renew comedy Flight of the Conchords for a second season.
