He was heavily criticised as producer of
Doctor Who (1963),
especially by
Mary Whitehouse and her National Viewers' and
Listeners' Association, for introducing more horror elements into the
series and sanctioning more graphic depictions of violence and gore.
Despite this criticism, the series enjoyed many of its highest viewing
figures during this period, with 44 episodes winning more than 10 million viewers, making him by some measure the most successful producer of the series.
