I think we'll see some of the "lessons learned" in this episode in the new Doctor, they'll be defined by this.
I really liked that version of Capaldi in the role, a proper war weary version who's tired of it all and just wants a way out. They probably should've had him in that darker situation all season, instead of the embarrassing mid life crisis shite. Agree about the other Doctor stealing the show, though.
Never seen Whittaker in anything so intrigued by how she'll do in it, biggest problem is Moffat.
Apparently Moffat is also gone, even more intriguing now
