Doctor Who
Thirteen actors have headlined the series as the Doctor. The transition from one actor to another is written into the plot of the show with the concept of regeneration into a new incarnation, a plot device in which a Time Lord "transforms" into a new body when the current one is too badly harmed to heal normally. Each actor's portrayal is unique, but all represent stages in the life of the same character. Together, they form a single lifetime with a single narrative. The time-travelling feature of the plot means that different incarnations of the Doctor occasionally meet. The Doctor is currently portrayed by Jodie Whittaker, who took on the role after Peter Capaldi's exit in the 2017 Christmas special "Twice Upon a Time".
Tenth Doctor
The Tenth Doctor has been extremely popular amongst the "Doctor Who" fandom. He received critical acclaim for his complexity and humanity and is considered one of the greatest incarnations of the character. The BBC went as far as to consider ending the show in 2010, thinking it would fail without Tennant. In 2006, readers of "Doctor Who Magazine" voted Tennant's Doctor "Best Doctor" over perennial favourite Tom Baker. He also won the National Television Awards award for Most Popular Actor in 2006 and 2007, and the award for Outstanding Drama Performance in 2008 and 2010. In a poll conducted by "Radio Times" in March 2007, Tennant's Doctor was named the "coolest character on television". IGN ranked the Tenth Doctor the best Doctor in 2011. In 2013, IGN again ranked Tennant as the best Doctor, along with the "Daily Mail" and "Radio Times", with Billie Piper also being voted as best companion. Users of Plusnet also voted David Tennant as the best Doctor in 2013. Users of DoctorWhoTV also voted Tennant as 'Ultimate Doctor' in 2013. Voters on "Digital Spy" also rated Tennant as the greatest Doctor in 2013 with 50.05% of the votes, and again in 2015. A poll in November 2013 revealed that Tennant was considered the greatest Doctor with 33% of the vote, a clear 10% lead over 2nd place, Tom Baker.
Readers of "The Telegraph" voted Tennant as the greatest actor to play the Doctor in 2014.
