Doctor Who: EVERY Fifteenth Doctor Episode Ranked Worst To Best

2. 73 Yards

It's all about Millie Gibson here and she shines. 73 Yards was the first Doctor-lite episode in this run and, though Ncuti is very much missed, he also isn't - thanks entirely to Gibson's performance here. 

73 Yards is an episode that promises, delivers, and teases quite a lot. Losing the Doctor the way that she does, gaining the mysterious woman, joining (and leaving) the ranks of UNIT - it's a lot, and Ruby careens through it all with a maturity that Gibson nails in every scene.

While the fake-out in the pub is a good slice of comedy, thankfully, the rest of the episode leans into the horror of her situation. Everyone who encounters the woman looks at Ruby with dread, including her own mother. Though she does, of course, use this to her advantage in the future (take THAT, Roger ap Gwilliam), there are so many uncomfortable scenes that one can't help but feel Ruby's struggle through the years.

Though there is a reset button at the end, 73 Yards is a key episode in this new era of Doctor Who. When everything is done correctly, as it is here, Doctor Who can still deliver the finest storytelling this side of the BBC. 

And, speaking of storytelling...
