While not just about The Curator specifically, I do want to say that I'm tired of Doctor Who never answering anything interesting about The Doctor. A character doesn't have to be 100% mysterious to be enjoyable, would it actually kill the franchise to give some definitive answers? Doctor Who is not going to lose popularity because they, as a random example, name some of the kids The Doctor had before leaving galifrey (which several Doctors have mentioned having, and susan's existence would confirm anyway). To be fair, some people have tried that and its gone terribly (those stupid fucking looms and the cartmel masterplan), but its still something I'd like to see eventually.
