Doctor Who: 8 Unanswered Questions From The Thirteenth Doctor's Era

8. Why Did The Flux Make No Sense?

While Thirteen's final series was an improvement on its predecessors, that's not saying much. Given that the overall plot of Flux was a half-baked mess, the serial was only mildly tolerable at best.

So, ultimately what was "the Flux?" The immediate answer is that the Flux was meant to be the massacre of the universe, which the Division incited. However, the Flux's purpose and extent remains convoluted to the point that it makes no logical sense. It appears to have ripped across the universe, destroying planets and civilisations by the end of the first episode, but as viewers, we find planets with active populations in the following chapters, contradicting Thirteen's quote at the end of Chapter One:

"The end of the universe. I always wondered what it would feel like."

The end of the universe? Well, actually, the end of a handful of planets that weren't relevant to us in the first place. And by the series' conclusion, with all those galaxies, planets, and solar systems supposedly still wiped out, the Doctor and her companions don't even care anymore.

The entire plot of Flux appears to be a buzzword, to presumably raise the stakes. It contains so many illogical and contradictory elements that we, as an audience, are lost within multiple dead-ends. Like, come on, what the Flux was happening here?!
