I’ve just finished watching all of the Jon Pertwee episodes of Doctor Who. While there are no bad doctors, per se, I find his portrayal to be one of the weaker ones. His bad qualities of being rather patrician, snippy, and generally a bit insulting sometimes outweigh the fact that he’s one of the few cool Doctors. The gadgets are a bit silly, too (Whomobile).
On the other hand, he is fun and rather charming–there is definitely something plainly likeable about him. When paired with Sarah Jane Smith he became more enthusiastic, but how much of that is Elisabeth Sladen?
My current ranking based only on Doctors of whom I’ve seen every episode:
1. Tom Baker
2. David Tennant
3. Jon Pertwee
4. Chris Eccleston
On to the Trought, who I suspect will rank highly. I also need to finish one season of Matt Smith, but he’s probably above Pertwee for me.
