Big Reset Switch
As long as the writers don't fall back on the Big Reset Switch then I don't care about the sex of the Doctor. I'm still annoyed about the way "The Doctor persuades the Master to stop, and the Paradox Machine is destroyed. Time snaps back, and the events of the last year are erased and the Toclafane disappear." (https://en.wikipedia.org/wiki/Last_of_the_Time_Lords) type resets occur and nothing that happens matters because there are never any lasting consequences.
