I enjoyed it. I suspect if I were versed any in Nigerian/African culture and mythology I might have gotten more out of it.
So won't say much about that part, because I don't feel qualified.
Is this the first time we get a Doctor Who episode without a single white person (outside of the story telling flashbacks)?
And did I imagine things or did the Doctor pick up a little bit of the local accent, which would make sense with as much as he considers himself part of that community.
I like that we get glimpses of his life outside of the wild adventures.
He likes to take his time now to stop running every now and then and take refuge in a save space. A very mental health care thing to do.
The Doctor still forgets his pre-Hartnell lives most of the time. He points out it's the first time in this black body for him, but we get a glimpse in the same very episode of the fugitive Doctor (yay surprise Jo Martin!). But he only has impressions not tangible memories still until he gets solid reminders.
It's interesting that the backstory we get for him here is a story untold. Quite the irony.
Obligatory all the Doctors montage!
Mrs Flood appears randomly without any impact on the story whatsoever, but as Mrs Flood, Belinda's neighbor.
I was seeing wild theories on YT before this, totally going wild with theories. That we might get big fundamental revelations. Like Belinda being a Time Lord or even a future version of the Doctor, just from the intercuts of the Doctor in the barber shop and her in the TARDIS reacting to the time and space shenanigans. Apparently that had to mean that she unlocked memories from a fob watch or some such!
The disappointment must be immense. XD
Vindicating remains a side quest that goes without a hitch and is quickly done away with.
Belinda telling the Doctor that he has to get her home every single episode is getting a bit old. I think we get it.
They do not explain why that particular time and place helps with that, or I missed it.
