Why He Should: Its not much of a stretch to say that Whithouse and Roberts are the two most similar writers on this list. Both writers enjoy their comedic escapades (Whithouses Vampires of Veniceis an extremely funny episode), but Whithouse has proven to be more adept at writing intriguing, psychological episodes. Series 6's The God Complexis a hugely underrated examination of the Doctors psyche, and Series 7's A Town Called Mercy is an interesting, albeit tired presentation, of the Doctors guilt over the Time War. Seeing an entire season planned out by Whithouse could be an extremely involving watch, and would fall in line with Moffats more introspection-heavy Series 8. Why He Shouldnt: There really arent many obvious downsides to Whithouses selection. His continued involvement with the show makes his selection fairly likely. Why is he ranked third on this list? The next two selections would be less likely choices, but theyd also be far more dynamic.
