When did gender become an issue, beyond you throwing it in just now.
Nope, not saying she is above criticism, actually never even entered into a gender issue, I actually like her as the doctor, not my favorite, in the top 5, but nowhere near the worst.
I am simply stating that the "writers" of the show lost me by bringing back a character that most clearly died in 2 generations simultaneously and did not regenerate in either after death. And to add to it the last version of the master was actually becoming ally of the doctor....now, the master is back and evil as ever......nope, they lost it this time IMHO
