Oh I see, no I'm happy with that.

I mention the comparisons to other media because that media did it well and Flux didn't. You see the flux a handful of times but in the end it's just something happening on the background whilst these immensely unoriginal and boring supervillains wander around being similarly uninteresting. Even on a more basic level, it's yet another antagonist destroying the entire universe. Doctor gets between universes again, just gets jerked around constantly and only ever reacting to things because even she doesn't know what is happening. And people get teleported around constantly, often as the means it escape from danger which is unspeakably cheap, a man who has barely seen a lightbulb steps inside the TARDIS and is only mildly surprised by how completely impossible everything he's seeing is. Episode ending cliffhangers not resolved but subverted within a minute of the beginning of the next episode.

In what world is it too early to "jump" to immortal god, considering that's basically what they said in the show? Thousands of lives, she doesn't die she regenerates indefinitely forever. She IS immortal and that's the power of a god. Previously there have been references to the doctor appearing godlike due to the basically magic-seeming TARDIS, her tech, being benevolent, helping out everywhere and then disappearing. Well now it's not a naive, yet charming notion from a lifeform that's not advanced enough to understand. She IS one. She is no longer the roguish timelord objector going on adventures, which is the dynamic I liked.

Future huge story reveals will be about her past, and it'll just be unknowable, impossible to empathise with things like "oh it turns out I'm an ancient god" or "it turns out I'm the last of a different and even more powerful race now" which I think would actually be worse, imagine wading through all this shite just for it to basically be the same as before.

I like the traveller encountering problems and fixing them setup, I don't really like the "person showing up to a random problem happens to be the most important person that's related to that problem and also in the universe" really, especially when she's a god. You say you won't mind unless the doctor gets superpowers, but I wouldn't be surprised if something similar turned up. I bet there's a thing the doctor will have to do because they're a powerful ancient race, the only that race could withstand it.

On the other hand I didn't hate the Christmas special, so we will see. At least the butcher that wrote the flux is gone.
