10. The Lonely God
When Russell T Davies revived Who in 2005, he reseeded the idea that the classic series had started, of the Doctor being a god: ancient, alone, non-violent yet dark, and more powerful than anyone else in the universe on his chosen day. It's an idea that ran through every great Davies epic, from 'The Parting of the Ways' to 'The Waters of Mars', and in most resolutions, Davies actually eluded to this allegory. Often, the day was saved by a godlike action; the Doctor sent the Daleks to hell in 'Doomsday', was resurrected in a Jesus-like way in 'The Last of the Time Lords' and even fought the devil in 'The Satan Pit'. His opposite, the Master, twice had plans to change the human race and become their god, and the Time Lords' ultimate plan was to become creatures of consciousness, like religious deities. The Doctor's faced opposites in basements ('The Stolen Earth') and has been there at the start of worlds ('The Runaway Bride', 'The Doctor's Daughter'). That's a lot of subliminal messaging telling us how powerful he is. And even companions, Rose, Donna and Jack had their time to absorb godlike powers and prove that they were equal to the Doctor. Because that's supposed the power of God, I suppose. Poor old Martha though was only ever given a key to rip the Earth apart. Poor Martha.
