Lord High Pooh-Bah of All Books I Survey
I think my favourite companion is probably... Hm. That's a hard one. I'd have to say both Barbara Wright and Ian Chesterfield. Not only did Barbara and Chatterton have to put up with the Doctor's constant snide remarks, subtle insults, and all-around being the grumpiest old man he's ever been* but he's also the one who got the Doctor started on the whole "galactic hero" thing, what with their constant insistence on interfering with history and doing the right thing even when they know it's not likely to help in the long run and not smashing cavemen's skulls with rocks. Here's to Wright and Cheshireson; the teachers who taught the Doctor right from wrong.
As for least favourite, that's easy. Rose. Primarily, I hate her infatuation with the Doctor, which started New Who's trend of every female companion either falling in love with the Doctor or being remarkable for not falling in love.** There's her jealousy over the Doctor having previous companions (*gasp!* The "900"-year-old*** man's had friends before! What a shock!) There's her attempt to break through reality - a thing she was told was cosmically dangerous and potentially universe-ending - just to get back to him, there's her basically dumping Mickey for the Doctor... I'd probably have liked her much better without the awful romance subplot. Couldn't have liked her worse, that's for sure.
* Not to mention constantly getting Cherrington's name wrong accidentally-on-purpose all the time. Although - after a certain episode's sheer slander - I should point out that he was never particularly sexist towards Barbara or Susan. If anything, Chisingholm got the brunt of his grumpiness, since he was competing with the Doctor all the time.
** That's one thing I like about the latest season, at least - no love interest for the Doctor, and the companions aren't even particularly obsessed with her. If only the actual stories had been better, and not mere vehicles for virtue-signalling... well, maybe next season will be better.
*** And if you pull the other one, it'll play "Oranges and Lemons".
