Monsters Who Came Back For More ! Monsters Who Came Back For More ! was a 2 | entertain DVD documentary in which Nicholas Briggs and Peter Ware examined the reasons why monsters returned for further adventures . Briggs explained that he often felt empathy for the characters when they were clearly afraid . For this reason he fondly remembered the Second Doctor era as Patrick Troughton could could portray fear very well . The first section , " Shadow of the Daleks " , explained how the immediate success of the Dalek s led to their return in " The Dalek Invasion of Earth " . The various attempts to better the Daleks were mentioned . Briggs dismissed the notion that the War Machine s could be a recurring monster , despite their " Blue Peter " presentation as " bigger Daleks " . Ware and Briggs then listed their " top recurring monsters " with Daleks and Cybermen being unanimously on top . Briggs went with Ice Warrior s as his third while Ware went with Sontaran s before changing his mind and going for Weeping Angel s . Both agreed that the Robot Yeti were worthy of praise despite having only been in two stories . Briggs went so far as to jest that he had a " Yeti sphere " in place of a heart . As to why monsters came back , Ware suggested it was a cost - based decision as the costumes could simply be reused . Both Briggs and Ware agreed that viewers liked to see old monsters as they were familiar with them . Ware compared it to a concert where people wait patiently for the band to play their most famous song . Briggs saw how well a monster was remembered to be important . Particular attention was made to the return of the Macra with Ware viewing it as a crazy decision only a fan like Russell T Davies could make where Briggs took a similar view suggesting only some fans would identify the species while others would just see it as " a crab monster " . Next on the agenda was the question of whether the best monster returned the most times . Both Ware and Briggs disagreed with the latter evidencing the Zygon s . Ware explained how monsters were often better in their returning stories than their debut . As examples of this , he gave Daleks , Cybermen and the Robot Yeti . Briggs viewed the changing face of the Sontarans and criticised how vastly they changed it from the established design of the " The Time Warrior " and saw their redesign for " The Sontaran Stratagem " to be faithful to the original , albeit in blue . Slaar was viewed favourably as he made the Ice Warrior s more sinister as he could articulate better . The section " Everyone has a favourite monster " , saw discussion as to the best monster . Jon Pertwee favoured the Draconian s while David Tennant chose the Zygons . Ware explained how the " Doctor Who Magazine " comic often brought back old monsters as did Briggs in terms of " Big Finish " . If he was in control of the TV show , Ware and Briggs both agreed that the Draconians and Zygons should return . Ware suggested that a well - realised Bandril could return but Briggs viewed this as ridiculous . In closing , Briggs commented on how the shear amount of spin - off media meant that every story would likely have a sequel sooner or later and that every monster deserved to do so .
