Nearing the end of the series, it seems that the writers of The Prisoner were trying desperately to grasp satisfactory ideas and just get them done. This episode proves a fine example of such. More often than not they managed to do this and get it right. Unfortunately, the writers fall flat on their face in their attempt to produce one of the bizarrest and comparatively worst of the entire series.
Looking at the plot line, the episode doesn't relaly seem that bad. However, as the story unravels, the poorly-formed plot twists and generic, non-sensical writing, intertwined with a string of random events which happen to way too quickly turn the episode into someting that is almost painful to watch. What is rather confusing is that this inferior episode is followed by two of the series' best, "Harmony" and "The Girl Who was Death."
Every series has to have a bad episode. This is an odd, temporary, turn into mediocrity for this otherwise compelling series, which fortunately is brought back to life with the next episode, "Harmony."
