Re: Matt Smith's Departure Confirmed.
There's no reason whatever that a female Doctor would have to be any more 'normal' than the current incarnation. She could still be an insensitive, self-loathing, solitary creature that needs an external presence to round off the rough edges. It would, however, be interesting to have a female Doctor to counteract all the shrieking in terror that the companions usually get up to.
Some say that he haunts the halls of the Top Gear production office and that, if you listen closely, you can hear his wails around Gambon.
All we know is that he's not The Stig, he's The Stig's drowned predecessor.
