I watched it and liked it. The confidential afterwards explained more. There was something about the woman but my daughter was hanging off my neck so I didnt hear it.
I do agree, part 1 was awesome. And when you saw Timothy Dalton rousing the time lords I thought the battle would be epic. Not a few people standing there on a white screen waiting for something to happen. Oh and nice glove Tim.
The master was thrown into the time war with the rest of them. They showed a better shot (in fact they showed a few better shots) in the documentary afterwards that showed it happening clearly.
The Doctor didnt die, but Russel T Davies and the whole production crew have been replaced along with David Tennant so they wanted to convey that changing his face was also changing who he was. So in essence Tennant died.
Donna had a failsafe put inside her by the doctor (ooer) that if she tried to remember she would black out and apparently take down any Sim clones in the process! but I think if she saw him and he told her she would bite the bullett.
