Some thoughts on each of the first 12 Doctors, leading up to a separate post about Number 13, Jodie Whitaker.
1. William Hartnell: The "grumpy grandfather," always finding his traveling companions lacking (even his own granddaughter), but not without affection for them.
2. Patrick Troughton: The "jolly grandfather," always good for a laugh, but ready to defend his companions to the death.
3. Jon Pertwee: The "daring uncle," full of tales about his adventurous past and taking his companions on equally exciting trips.
4. Tom Baker: The "madcap uncle," incredibly intelligent and incredibly wild, you're never sure if he's being brilliant or just crazy.
5. Peter Davison: The "big brother," just a bit older and wiser than his companions, but protective of them.
6. Colin Baker: The "critical uncle," his disagreements with his companions never seem to come from any sense of affection.
7. Sylvester McCoy: The "screwball uncle," not as physically wild as Number 4, but more given to absurdities as part of his plan.
8. Paul McGann: The "heartthrob," Lord Byron in an alien's body with a time machine.
9. Christopher Eccleston: The "reformed bad boy," ready to drag you into something you really aren't ready for.
10. David Tennant: The Doctor as "Mr. Darcy," the brooding, handsome guy every girl falls for...but who deliberately keeps them all distant.
11. Matt Smith: The "daft best friend," the one guy in every circle of chums who maintains a platonic relationship with all the girls--except for the one who he can never quite keep hold of.
12. Peter Capaldi: The "cranky neighbor," always on the verge of saying "Stay off my lawn," but in reality the neighborhood watchman, keeping an eye out for the dangers you don't know are lurking.
Next time, a more extensive look at Number 13, Jodie Whitaker and why she's so disliked by one very vocal segment of fans (and no, it's not entirely just because she's female).
