The afore-mentioned "Magnum, P.I." had a premature series finale, as well. At the end of the seventh season, protagonist Thomas Magnum was to be killed off, which was intended to end the series. The final episode of the season, "Limbo", after seeing Magnum wander around as a ghost for nearly the entire run-time, closes with him appearing to walk off into heaven. However, following outcry from fans, who demanded a more satisfactory conclusion, an eighth, final season was produced, to bring Magnum "back to life", and to round the series off. The mystery of whether Higgins was Robin Masters, or not, was a highly anticipated series finale reveal. The mystery still has yet to be revealed. A number of other episodes also make reference to supernatural occurrences and the seeming existence of ghosts.
