When CBS decided to cancel the series in late 1979, the series' producers decided not to resolve all the story lines. This was done in part because the producers claimed there simply wasn't enough time to re-write proper conclusions for all the story lines. Another reason was that the producers were hoping that another network would pickup the series, but this was not the case. Consequently, the final airing of the series, ended on a cliffhanger that was never resolved. Longtime fans were shocked and outraged that the story lines were left unresolved.
