Doctor Who: EVERY Fifteenth Doctor Episode Ranked Worst To Best

5. Dot And Bubble

Dot And Bubble is an uncomfortable watch. 

Set in a society that is dominated by social media (sound familiar?), the episode draws the viewer into the daily humdrum of Lindy's life. She gets up, already logged on to her social hub, and narrates her seemingly idyllic existence as she goes. All is well, mind the slug, and don't forget to ignore friend requests from outside your network. 

God forbid you'd have to have an original thought.

Lindy Pepper-Bean has a distinction in the pantheon of Doctor Who characters. She's one of the most universally loathed characters in history - all of which stems from the final act of the story (though the clues were there throughout). Betraying Ricky, directly causing his death, and exposing her racism - all within moments of each other - delivers a vicious gut-punch to the audience, one so used to seeing the Doctor win, or at least lose like a hero.

Here, the Doctor is powerless, confronted by the ignorance and stupidity of racial prejudice. Knowing that the reveal was one of Ncuti's first scenes filmed only serves to highlight how incredible he is in this scene.

This episode is not an easy rewatch but that is the point.
