Doctor Who: EVERY Fifteenth Doctor Episode Ranked Worst To Best

3. Lucky Day

Jonah Hauer-King looks like the perfect 'good guy.' He has those disarming looks, his smile could melt butter, and Lucky Day seems poised to introduce Conrad Clarke as a recurring love interest for Ruby Sunday.

The reveal that Conrad is a grifter who excels at spreading lies, hate, and fear is executed perfectly. The audience felt for this character, believed him when he said all of the right things to Ruby. So when he comes out as a pathetic person using pain to push their own agenda, we are as shocked as she is. Having spent a season learning to love Ruby, watching her being attacked by this man is foul.

Of course, if it weren't and if none of the shock factor landed, then Lucky Day would have been a bit of a 'message over matter' episode. Peter McTighe used the brief - explore toxic, online hatred and lies - to create a narrative in the modern world. When so much online discourse seemed intent on breaking people down, characters like Conrad seem like the Hydra - chop off one head, two grow in its place.

Lucky Day gives us some truly great moments with Kate Lethbridge-Stewart, some affecting moments with Ruby Sunday, but also gives us the first really Doctor-esque speech from Ncuti's incarnation. Though this version of the Doctor is from a little earlier in the timeline (it is Conrad who informs him about Belinda in the first place), their shared scene in the TARDIS is a stark, grim classic. 

The standard Mrs. Flood cameo does little to dull the toxic shine on Lucky Day. Though Conrad may not have lived up to the promise of this episode when he returned, this was a true Doctor Who villain, armed with a keyboard instead of a gun.

Except for the part where he also had a gun.
