BELIEVE IT BRUV.
I'm serious. Jodie Whittaker starred in a cult classic SciFi movie called Attack the Block, which is now required viewing.
Oh yeah. That's Finn from Star Wars teaming up with the Doctor to fight off aliens. This is gonna go off the geek-o-meter, mates. Allow it.
In the meantime, this is great. The show is opening up the gender roles in science fiction more than it's been in ages. We've had strong female roles - Scully, Buffy, Xena - and we've had strong female leads in established franchises - Janeway on Star Trek, Starbuck and Athena on the reboot of Battlestar Galactica - but this is a major step: This will be a strong female lead in an ICONIC role.
Icons exist beyond the stories that birthed them - Sherlock, Bond, Kirk, Spock, Superman, Batman, Spiderman, just to name a few - and icons have a great impact on the cultural trends of the past, present AND future.
As much as a successful Wonder Woman movie is groundbreaking, as much as having movies like Mad Max Fury Road promote positive imagery of women, to open up an existing role and character as important to SciFi geekery as the Doctor will pave the way to equalizing roles between genders for the next generation of shows and characters.
So to all the haters out there, grow up. Women have been into science fiction as long as the men, and they've been writing their fanfic and making their cosplay and pining their dreams of heroic escapes same as you.
These are good times ahead for geekery.
