Production Errors

  1. There is a lot of attention paid to the fact that Mr Popplewick keeps a quill behind his ear, however the quill in question only appears when it is mentioned 

Working Titles

  • The Fantasy Factory

  • Time Inc.


A lame two-part episode which does not end the already dead, negatively received Sixth Doctor tenure on a high note. A cheap and lacklustre production that uses plot points from the classical acclaimed The Deadly Assassin and does nothing in the slightest to use them to benefit the story. The last ten minutes turn into a run-around resolution with a lot of shouting, terrible writing and awful effects whilst tying up all loose ends from the last three adventures in a rushed manner. However, in the process more questions and dead ends arise which are never ever answered. More childish name calling, supposedly ‘surprising’ plot twist are not that surprising and an ill-written ending. The plot takes time to tell the audience that Peri is still alive and married to a King, good for her, why change this? The Master appears, yet again, on a screen, to do nothing but provide some exposition. For a final episode for Colin it's really bad and does not reflect Colin’s time on the show in good light. *
