Grouch time!
I thought was OK, but all the usual problems of slow pacing and inward looking self congratulatory monoluging rather than plot.
It failed the wife and kids test by some margin. Elsie (9) was very excited to watch it with dad, but walked off - Joe (12) has no interest in watching it, despite being a Potter fan and currently reading Charley's War!) - Clare (wife) complained it was "for the fans" - she defends RTD era Who as very watchable, and I'll give her that - be careful what you wish for I suppose, as Moffatt has only intermittently reached the heights I hopedd, preferring to squander interesting ideas ("Hey it's an interesting idea, I have to DO something with it???")
Firsst Doctor is sexist chump - great. One or two jokes to that effect, fine (s long as you don;t labour them as here), but lose/cut the tell dont show of Capaldi's fan serving "never cruel or cowardly" speech and beef up the reason for the Firsts appearance and dilemma....
This "I don;t want to die/go" stuff, where the back room movements in the show become meta on the screen.... It isn't inherently bad, but when it is so blatant... we get you are leaving Moffatt, and you don't want to. We get that you think Doctor Who CAN be a fairytale, and are using the old Doctor to represent the "mingmongs" who won't buy into moon/egg shenanigans and are probably really, like, sexist and stuff (in 50 years time, will we have Doctor 25 calling out Tennant and Smith for their "shagging across time" and porn loving Ladisms?)
On Chris Evans radio show the other day, the producer was leaving, so they had about 10 minutes of backroom people talking about how great she was... it was excruciating radio (well, more so than usual for Evans) and shoed no self awareness that there is an audience tuning into to this that has no interest in.
Which is a shame as the basic "ideas" were interesting, as is generally the case.
