I agree completely with that last post - the Time Lords were never as all powerful as they liked to think of themselves, but they were arrogant as if they had created the universe for themselves and just allowed other beings to exist.
The Doctor has a lot of that attribute himself, more now than before the Time War, when he was the first to put them down for that attitude. Possibly as he feels he has to make up for them. <g>
But anyone who remembers before they were killed off, that it really didn't make a lot of difference in the universe, or the story. They were a staid, do nothing lot that only acted up once in a while to haul the Doctor home and tell him how much his behavior embarrassed the rest of the planet. That was pretty much their function, to have somebody who could yell at the Doctor like the naughty school child he was, and could seize control of his ship if they got serious about it.
The rest of the universe wasn't half as impressed with them as they were with themselves, and when attacked, they were typically not that hard to defeat, being unable to admit their tech wasn't the most superior in the universe, and therefore no serious interest in improving things. It was their ego that was unstoppable.
Time War changed all that apparently. Not a bad story, but I admit, I liked it when they were shown to be 75% ego and staid tradition, with 25% time tech to back them up.
The ep with Idris kind of brought back those days for a minute, a bunch of lost timelords easily lured in and beaten, Idris's longing to escape staid old Gallifrey and the twist of her stealing the Doctor, the only one she found willing to go exploring with her in that stiff necked lot <g> was the sort of fun I loved to see explored.
I remember reading an 8th Doctor novel where his tardis had become a woman - she was a strange robotic like thing who moved stiffly thru various emotions, logically finding no use in them, and wondering why she felt compelled to try to save folks she couldn't save. Idris was a wonderful relief from that, emotions she understood, she clearly always had them, and if she didn't understand her body, she certainly threw herself into every aspect of it to enjoy her less than an hour of life with it as much as she could.
The bit with Rory and Amy was pretty good - so many fans seemed to be wondering if Amy really appreciated what Rory has gone thru for her - seeing his love turned into an obsessive hate in that little vignette was good answer for that question, showing her fears of not being able to match her love and deeds to his, that her failure would someday cause him to realize she wasn't worth all he's sacrificed - a good scary way to tackle those questions.
On the other hand, when Idris rejoined the ship, I didn't feel sad at all. It seemed to me that she wasn't dying, or losing herself, just shifting back to her old form -one that was always intelligent and alive - and the only thing that changed was the talking. And I'm not sure that the talking is entirely done for good. I mean, she's always managed to ring that cloister bell, whose to say she wont find a way to talk with him again? Not all the time, as that would reduce her a bit, so many scifi stories have a woman hologram talk for the ship, and what would that do his future life with River if his ship and partner chose to view her as competition? But sometimes, on special occasions, I can see her coming back, holographically, or a disembodied voice.
(I'd have picked the 13th Doctor's death as the sort of occasion for it - and in the back of my mind I could see a great story where she saves her thief and finds him a new body, so that she wont be alone without him. Of course the dreadful hint that they are completely skipping the long awaited story of the 13th Doctor put a kabash on that.) They did say for certain that a Timelord can switch sex on regeneration, tho, which is the first time that was ever more than fanwank and idle chatter.
The characters in the House were fun and comical - evil without really being maniacal about it, they just accepted their function was to be evil, and well, what can you do? The niece's? death in the beginning was in much the same manner, she was the only one who voiced how scared she was, and everyone agreed calmly she should be, "I should say so."<g>, but neither she nor they seemed inclined to fight it.
The uncle was even calmer about his own death "I'm against it, but " *shrug* "well ..." It was sort of like a visit to the comical villains of Les Mis, the acceptance that their role was to be bad, and rebelling against your god-given (House-given, in this case) role, is sheer irresponsible nonsense.
