It would probably still be more captivating than Revolution of the Daleks.
Most of us have seen more dry walls than a redo of "Dalek civil war because one faction isn't controlled by Davros and/or isn't pure Dalek DNA" (the count is four or five, of which half these instances didn't even take place on Earth regardless of time period - scary but true in a show that can go anywhere in time and space...) And yet hearing Tennant talk about that is apparently more rewarding despite the number of dry walls one has seen... that definitely is sad, especially if all he's going to do is sit there and do the "Wibbly wobbly timey wimey humany wumany, have some tubby custard you awesome thirty year old I'm treating like a toddler" sing-song act, complete with - why not - a chorus of belching wheelie bins to ensure the show remains classy for all... Chibnall brought in some promise and potential through his tenure... in ways his era is so good but in others it's worse than what's preceded it...
...but I'm getting off track. Even for the Holiday Special, despite using another-destruction-of-Gallifrey as a theme for series 12 and ends that on a cliffhanger, there was something of interest... then he sidesteps it for a lame one-off when it might have been easier to segue in dialogue that puts the special in an earlier part of the previous season.
On the positive side, I really do like how he's keeping Dalek stories within their own direct and immediate continuity, which is rather clever, and "Revolution" > "Resolution" by a country mile... I almost wish he sidestepped the prison subplot, which seemed like a quick throwaway (most of the story has a lot of vignettes all worthy of expanded detail, of which none gets any.)
Series 13 looks sort of promising, or at least hints at an explanation of how he doesn't have to rely on "The Master lied, again" trope so he can have his retcon about "the Doctor is from a magical other universe" that a later showrunner will undoubtedly be quick to change (with or without the muiltiverse cliche, even though some people say that would be disrespectful of Chibnall, even though what he did arguably disrespected a larger number of showrunners before him), but "the multiverse" has been used in Star Trek and other recent franchises to the extent of "What's Chibnall and his ensemble going to do that will really one-up it?" Hopefully the new companion will be a decent foil between the Doctor and Yaz. All that said, his take on "let's destroy Gallifrey again" is actually better than a generic "Dalek Time War For Teh Feels, complete with generic baddie time lords", but how many more times in a two-decade span will that trope be used by future showrunners as an anchor for supposedly compelling drama? It's getting silly, and are there no other ways to engender drama that doesn't come across as needlessly derivative? Well, if such drama can be made without trying to force or pretend to be "grandiose epic"...
If Whittaker is leaving, and if she is she is, and if she isn't she isn't; if anything she's the first actor to take on the role with such a level of apparent dispassion. Maybe that's why Jo Martin was a greater success in her five minutes on screen; she put in above and beyond what's on paper and comes across as being properly engaging and interesting and as if she actually wants to be there. How did Chibnall get so lucky in finding her? (I'll admit, The Division was novel. A proper use for the Judoon and elevating them was interesting. I had no clue that the Fugitive would be a different incarnation... And given some decent backstory, in a way that I wish had been done for series 11 so his era would be properly strong from the get-go. Chibnall has brought in some neat stuff but then trips up when he doesn't need to.
