Prerequisites: Season 1 (not Series 1)

I actually ended up liking Lucky Day quite a bit. It's no masterpiece, but it lacks many of the flaws I can point to in the previous episodes. The twist with Conrad genuinely surprised me, and while I think his heel turn was a little clumsy in a few ways (it works less when you consider that widespread alien invasions have happened quite a few times before), it also worked very well. As 73 Yards showed, Ruby works pretty well as a solo protagonist, and I liked her here. Plus, that scene with Conrad and the Doctor at the end might just be my favorite Ncuti moment so far. For once, he felt like a distinct character, and I really liked his anger.
