Disclaimer: There are 38 posts before mine, so I assume there has been quite a discussion. As a latecomer to the party, I have not read what others wrote. The following are just my standalone thoughts.
I did not like Gallifrey 1.2. The main reason is that my suspension of disbelief was broken around the midpoint of the story. At the end of the third (?) timeslip, as far as Leela is aware (there might have been more that she didn’t register; I think there’s a hint in that direction later on), Leela is confused. Leela, who time-traveled with the Doctor. Leela, who lived among the Time Lords. Leela, who attends a temporal summit of the great time-traveling powers, does not realize that her déjà vu is related to time travel.
In my opinion, this is a pure plot device for listeners not familiar with time travel shenanigans, and a bad one at that. They could have had Leela realize what’s going on and dictate a message to K9 for Romana, catching up listeners without insulting Leela’s intelligence.
But she’s a savage, you say? In the same story, later on, we get a demonstration of how to show this without insulting her intelligence: Leela realizes what’s going on but puts it in poetic descriptions of “the yesterday before” and “another yesterday.”
As always, as soon as the suspension of disbelief is lifted, flaws in the story become much more noticeable. For example: Aren’t these all time-sensitive beings? Shouldn’t other people also notice the timeslip?
If they wanted to show the decadence of the “great” time-traveling powers, where are the male and neither male nor female “entertainers”? (At least I think there where only female.)
And what’s up with this repugnant delegate who turns out to be a psycho killer but has nothing directly to do with the main plot? I did not like this story thread and also feel it took up too much space, so Romana had to give a synopsis of the genius (and I would argue over ambitious) plot of the story (real summit, …) at the end because there was no room to “show” us what’s going on. Instead, we get an info dump at the end.
I probably could go on, but in the end: If the writers had not written Leela as clueless as long as they did, my suspension of disbelief would have held up, and the flaws would not have dulled my enjoyment of the story as much as they did.
That said, later on (too late to sway my overall impression, but still), Leela has some really beautiful lines. Beginning with her speaking poetically about the previous yesterdays and later finishing with her thoughts about reality in the face of time travels changing history.
It’s a shame the story did not end there, and instead, there had to be a final line from Romana.
So, Gallifrey 1.2 was not for me - 2.5/5 and a 4 to 5 out or 10.
