Personally, I absolutely loved the three specials (including this one). I love how zany and fun and sometimes dark they were. Wildly entertaining and surreal, as Doctor Who at it's best often is.
One slight note of caution: Up to this point, the only sign of Disney fingerprints has been the "Avengers Tower" UNIT base (a fun gag, I'll grant). I don't detect any US executives at Disney attempting to tamper with or water down the essential British eccentricity within Doctor Who so far. However... I am a little disturbed at what bi-generation might mean in terms of Ncuti Gatwa's Doctor. One might cynically claim this is Disney hedging their bets to have Tennant as a fallback in case US audiences don't take to a Black Doctor played by a gay actor. I'm sorry to be so cynical and raise the spectre of potential racism/homophobia, but I know how some of these Hollywood hypocrites think. Would this have happened with a straight white actor?
For better or worse, there really ought to be one Doctor (except for multi-Doctor stories) and it's time to let Ncuti Gatwa carry the reins by himself and have a good go of it.
