In The Woman Who Fell to the Earth, the Doctor has stolen part of the alien invader’s transport home.
The Doctor is an ancient god-like alien who travels through time and space righting wrongs and helping people through technology and progressive values.
Whether the new doctor is a woman, or Scottish, or whatever, change is the very nature of Doctor Who, and it is frightening to see this iconic character change.
The Doctor is physically incapable of not touching a big red button or walking by a fez without putting it on.
