YMMV / Doctor Who S18 E3 "Full Circle"

• Hilarious in Hindsight: Kind of funny to have a character named Login now. Good thing his daughter's name wasn't Password.
• Ugly Cute: The Marshchild, a creature that's essentially a baby swamp monster. In one of the first scenes in which it appears, it's shown peering at the Doctor from behind a fallen tree, its obvious timidity combined with its endearingly ugly face giving it an almost irresistible cuteness. That cuteness is only enhanced by a subsequent scene in which it's shown materializing in a spaceship corridor behind the Doctor, only to go scurrying back out of sight a moment later. It doesn't help that its subsequent ill-treatment by a bunch of (apparent) humans propels it firmly into Woobie territory.
