I definitely agree at the strength of the Doctor's speech about Time Lord being more than just biology.

As for Jenny's death/resurrection, I felt far more manipulated by her death, partly because it was so very obvious that it was going to happen. And so, as a result, I found myself caring much less about her during the course of the episode. Now, after she was dead, it was also clear that she would come back, but I was less manipulated by that because that suspicion only lasted some five minutes before it was confirmed.
