It seems like Doctor Who has been around forever and that's because it pretty much has. Well, in terms of television, anyway.
Debuting on November 23, 1963, the long-running British series has an interesting plot device that simultaneously works to usher in new actors to take on the lead role: regeneration.
The choice allows for an infinite number of casting possibilities, but in the 50+ years of the show's existence (darn that's a long time), there's never been a female Doctor.
The Twelfth Doctor, played by Peter Capaldi, "regenerated" into the series' newest doctor, who's being portrayed by actress Jodie Whittaker.
As excited as fans were for the show to make history, people had mixed emotions about watching Capaldi go.
Especially with his touching last words.
just got around to watching the new doctor who. FINAL TEN MINUTES WERE HEART WRENCHING. BEST REGENERATION SCENE SINCE 2010. EXTRAORDINARY.— Ewan McIntosh (@Ewan_McIntosh) December 25, 2017
The most perceptive of viewers noticed a visual callback to Capaldi's introduction/exit into the series.
But the excitement for Jodie, and her suspenders, is palpable.
Her introduction into the series already has fans smitten.
Although she's only uttered two words in the latest episode, people are already geeking out.
People seem to like that the writing team didn't make it such a big deal that she's a woman in the show and instead chose to acknowledge it in a normalizing way.
Others pointed out that the mere fact that a doctor is female now is a strong enough visual symbol.
Definitely got a bit emotional at that Doctor Who regeneration. As a kid I always pretended to be a companion when playing, never even occurred to me that I could play at being the actual Doctor, and now so many little girls will get that— Holly Nielsen (@nielsen_holly) December 25, 2017
Others are just excited to see the direction that Jodie takes the character in.
#DoctorWho was totally amazing and I'm too emotional now— holistic student (@Emotional_Bug) December 25, 2017
Final speech of 12th was great and touching. Words of Bill about "the hardest part is to let you go" too
I, personally, was in tears, when saw Clara
And of course, welcome, 13th! Can't wait for new season ✨🌙
How Capaldi's sendoff and Whittaker's simultaneous introduction was handled is also getting praise.
I'm actually so glad with the way they went about this episode, I've enjoyed the other regeneration episodes but I liked that this was different. It was funny, emotional, beautiful I guess that sums up this era which will be missed. Here's to the next🍻 #DoctorWho #GoodbyeTwelve— Niamh❤ (@Gillan_Lovato00) December 25, 2017
Goodnight, I’m so grateful for Peter Capaldi and Doctor Who. The episode was amazing and emotional and I’m in love with the thirteenth doctor. Bye xx— helena ✨ (@doctoorwho) December 25, 2017
For the most part, though, fans of the program are just geeking out hardcore.
And can you blame them? Whittaker's made Doctor Who history.
