In this part, the era of the Fourth Doctor, Tom Baker, is considered. We explore the 'Golden Era' of Doctor Who, looking at how the show developed into a far darker and scarier version, influenced by the Gothic Horror genre, and the resultant backlash from self-appointed 'moral guardians'. We also consider the economic troubles of the late seventies and their effect on the show before its regeneration just in time for the eighties. Along the way, three stand out stories are looked at in depth with plenty of clips from the full seven-year Baker tenure!
