I felt that Lucky Day started really strong, and managed to maintain this quite well. Around a third in (just before the twist), I felt it was starting to slip, but it recovered really well (due to the twist, which caught me completely off guard). I think that this is the most interesting way they could have done an episode with UNIT, and I enjoyed watching it.

I felt that there was some really nice directing throughout this episode, and I also thought that it all looked great in general. The special effects worked really well, and the music was largely good in my opinion.

One of the main issues, for me, come from some of the mixed political messages of the episode. I think that conspiracy theorists and missinformation are really dangerous, and the episode conveyed this well. However, it did also deliver the message that all authority is here to keep us safe and should not be questioned. Sometimes, this is very true. Other times, not so much. I think that it's interesting to note that the episode's writer, Pete McTighe, also wrote Kerblam!, another episode somewhat infamous for messy politics.

I also felt that the episode was not very subtle at points, and I'm not sure I liked how they did the social media short-form video segments. I also felt that some of Conrad's characterisation was a little inconsistent considering the twist.

On the whole, I enjoyed this and it far surpassed my expectations, but there are a few things holding it back from the top ratings.
