Turns out people seem to want a Female Doctor, to which I say NO.

The Doctor has always been an eccentric, slightly posh, completely bad British male. This should not change, it ruins the feel of the show.
And don't get me wrong, I'm not being prejudiced here! I'm all up for a black Doctor, atau a gay Doctor, atau any of that sort of thing, I just don't think he should become a she. For instance, how would we refer to him? He? She? It?
The Maths also doesn't make sense. Think of it. If the cells changing are truly random, then there would be a 50/50 chance of him being male atau female. There have been a minimum of thirteen Doctors. Doing some basic Maths shows that there is less than a 1% chance of him not being female until now, if he can change gender. Couple that with seven Masters before he became Missy, as well as Romana not becoming male, and anda get a truly low chance of no gender changing regenerations until now.
Personally I think Missy started the failure. It feels wrong for the Master too, and the Maths applies as well. I originally thought Missy was going to end up as Romana gone bad, atau something like that (which we should burn into Moffat's front garden).
To tell the truth, I would actually rather season 10 ended with the Doctors death than a female Doctor. Any female Doctors will not be canon in my book, atau any of the events that happen during their time.
