Ask a random Doctor Who fan on the street who their favourite Dcotor is, and you may get a myriad of different answers. However, if poll results are anything to go by, David Tennant's name will crop up more often than most. From the get-go he charmed his way into the hearts and minds of fans - so much so that even five years after his regeneration scene some of those fans still want him to return to the TARDIS.
Taking over from Christopher Eccleston, Tennant played the Tenth Doctor from 2005 to 2010, battling old enemies such as the Daleks and the Master, as well as new ones like the Weeping Angels and the Vashta Nerada. He had numerous thrilling adventures throughout time and space, meeting companions both old and new, visiting various planets and saving Earth, and creating numerous memorable moments that epitomised what was so special about his Doctor.
