Why do I keep seeing the complaint with Chibnall's term of the TARDIS being overcrowded? It's not like having three companions was something crazy. Quite a few times, in the classic era, there were, at least three companions. Most of the First Doctor's time had 3 or more companions. The second had 3 for a time, and the Fifth Doctor started with 3 companions (as well as briefly the Fourth). One could argue that the Third Doctor had quite a few companions, but they weren't in the TARDIS since he was exiled to Earth. I believe Chibnall was trying to get back to the classic era with three companions and serialized storytelling.

What Sony jail? Spider-Man is still part of the MCU. There's supposed to be a new film next summer, if it doesn't get delayed now that Avengers has been delayed (especially since they haven't even started filming it) He just wasn't going to be in Doomsday. For one, Tom Holland has been busy with The Odyssey then moving on to Spider-Man. There was also talk that the new movie would take place during Doomsday, so we see where Spider-Man is during the events. But unless they delay it, that may not be so likely. But it is presumed he will be in Secret Wars.

How many times in the history of Doctor Who have they brought back old villains thought to be dead. Whether it be the Master, Davros, or even Omega was brought back with the Fifth Doctor when he was thought to be destroyed in The Three Doctors. But they aren't really "gods". That was the point of The Story and the Engine. That the so-called "gods" have become that only because of the stories told about them. Omega was a legend in Time Lord lore. He also became very powerful after he entered the anti-matter world, being able to harness the power to create his own world within it. So he isn't necessarily a "god", but his power and legend make him seem like one. The same goes for the rest of the pantheon.

And what do you mean by "before she even existed"? She's always existed. She goes way back to the classic era and her, the Doctor (at least starting with the William Hartnell regen presumably), and the Master grew up together. The new regeneration is still the same person, just like the 15th Doctor is still the same person (even though he bi-generated). Mrs. Flood was Rani all along.

Yes. But she bi-generated. So we have two Ranis. Although the new Rani claims to be "THE Rani" while Mrs. Flood is "A Rani". It seems the new Rani doesn't like the personality of Mrs. Flood's regeneration, so treats her as a lesser version.
