I absolutely adore classic and revival who, but as much as I love them, the CGI doesn't always hold up decades on.

The Five Doctors is a story that I think is brilliant, balancing the fanservice, multiple doctors, multiple enemies, lore reveals, brilliantly, with being able to tell a spectacular story, but the one thing that always sticks in my mind when I watch it back with friends, is the time scoop. A silly little triangle floats down on screen, and we get a freeze frame of our characters. It's utterly hilarious how it doesn't hold up, and while I love it, it does take you out of the story a little.

Lux, in contrast, is a story I think we'll be looking back at in 40+ years and be astounded at. Every second Mr Ring-a-Ding is on screen just works. The cold open especially is one of the absolute bests in the show's history, Mr Ring-a-Ding crawling from the screen is spectacular, and really does just show the scale of the villian, you can't not be hooked.

As for the rest of the story itself, I think it's a wonderful blend of Scooby Doo (as the characters themselves point out), and The Giggle. A god-like being trapped in a closed down cinema with a caretaker at night, where 15 people have gone missing, that being using their powers, trapping The Doctor and the companion in a world relating to that medium, it's so so good, I can't help but love it.

I do think the 4th-wall break, while fun, did somewhat bring the episode's pacing to a screeching halt, and used up time that could've been devoted to better fleshing out the ending. I do enjoy Lux's defeat, and I think it's an interesting twist on the way the rest of the pantheon we've encountered so far have been defeated, but I do think that explaining the actual mechanics of it a little more might've helped the story somewhat. The missing 15 suddenly returning as well felt like an obvious ending, but the actual mechanics of how they did aren't really explained. It makes emotional sense, which is what I think should always be prioritised, but less so on the logic front.

As a final note, I do also have to give credit though to the side cast. Everything we get with them in just brilliant. They're no Silence in the Library or Under the Lake, but they've all got very clear characters and motivations, they're entertaining to watch, and none of them are forgettable.
