I loved Doctor Donna.
I think if it was an american network, they would have forced her to lose 30 pounds before they turned the camera on. It was just nice seeing a real woman. She's not obese or ugly anything like that, it's just she's not freakishly thin like Tenant was. And her life was shit. Not magical like Amy's, not young and incomplete like Rose's... just completely mundane and completely shit. And then the Doctor had to take it away from her, but give her a little bit of happiness in return.THOSE FEELS.
In america, she would have been freakishly thin.
Edit: And yeah, that Hartnell mock-u-mentary really WAS good. I mean shit, I started watching that thing expecting it to be sentimental, self congratulatory, and basically terrible. It surprised me a lot. It could actually stand on its own legs as an interesting story for a not-fan.
