Doctor Who: 10 Most Disappointing Concluding Episodes

8. The Masque Of Mandragora

Considering it features the most powerful entity in the Doctor Who universe, the Mandragora Helix, it should have had the power to keep going throughout four episodes. However, the writer of this story, Louis Marks, was selected for his knowledge of the Italian Renaissance rather than his CV on Doctor Who, which included one so poorly paced that an entire episode was edited out before airing. It starts out focused on the Doctor and Sarah Jane fighting the Helix with a few scenes of dull Italians discussing astrology. However, it gradually stops being about the Doctor - which meant that the script editor could apologetically patch in funny moments - and starts being about political infighting in Renaissance Italy instead. This story is split into two parts, the one rewritten by the absurdly talented man and the one which was written by the boring one in such a way that the talented man couldn€™t do anything. He was probably happy while everybody else was miserable.
