Doctor Who: the companions' best and worst performances (part 3)

Completing my alphabetical look back at the actors who’ve played companions on Doctor Who, and judging their best and worst performances. To start from the first chapter of this three-part essay, click here; to take a look at the Doctors’ best and worst performances, click here. In the previous chapter, I noted that writer David Whitaker had penned a lot of best performances: Hartnell, Padbury, O'Brien, John and -- if I hadn't eliminated "Enemy of the World" because of the dual-role aspect -- Troughton. I wondered if there were directors who, similarly, had been responsible for a lot of the actors' finest work, and a cursory look back revealed that seven of the best performances were guided by Paddy Russell or Fiona Cumming. They were, in fact, the only directors responsible for more than two. Both women: is that a coincidence? (And if we're looking at female directors, we'd need to add in Alice Troughton, who helmed Tennant in "Midnight.") I don't want to fall back on reverse sexism, but did the female Who helmers tend to devote more time to shaping performances than their male counterparts? As the kids say on social media, discuss. Meanwhile, let's finish our look back at the Doctor Who companions, below. As always, although I bold the actors’ best and worst performances, for easy scrolling, I vary the order in which I list them — so presume nothing.
