I'm surprised so many people are bringing up Ursula's fate. I wonder if people would be happier if she had been left dead. It would have been a more clear cut and less complex resolution, but I think the one we had played more strongly into Elton's thoughts about what is good and bad about the Doctor at the end.

It's a good point, though, the Doctor isn't shown to be what binds LINDA together. I had not thought of that.
