I've watched Doctor Who since I was little. Not any more.
Changing the gender of a legendary character who has been cemented into this nation's history has no effect on gender equality. It's simply pandering to all of these modern views. As a man I wouldn't be happy if they changed a character who'd always been female to male. It doesn't make sense.
I know they were 'testing the water' when The Master changed to Missy, and I wasn't happy then.
The show wasn't doing that well in my opinion due to lackluster scripts and now the ratings are surely going to be affected. There's way more people mad about this than they were at how annoying of a character Clara was (and she was really terrible!)
