It's weird that no matter what happens in a Chibnall episode it just all feels the same to be. Not terrible (usually) but just pretty flat. I have no idea what the plot of this episode was: something to do with the Death Star shooting volcanoes? When The Master stole the Doctor's regeneration or whatever I thought that could have been interesting as we might see the Master try to be the Doctor or something (and maybe he had part of the Doctor's personality now?) and Sacha Dewan played it well in the first scene...but it didn't really come to anything. He was just The Master in the Doctor's clothes for twenty minutes. What was with the little girl at the start? I thought it was the TIMELESS CHILD or something but then they said she was just an illusion (why was she in a box then?) It's amazing that Chibnall spent as long in his tenure on all this LORE that's going to be completely ignored from now on.
All the cameos were certainly the highlight and it's impressive that they kept the Baker, Davison, McCoy and McGann appearances secret. I haven't watched much of the old stuff so the companions didn't mean as much to me - and I won't comment on their acting because maybe some of them haven't acted for a long time - but I did notice they didn't even let Bonnie Langford speak.
I totally forgot the guy on the X-Wing who landed on the Death Star was a thing. Didn't he have a pregnant girlfriend he was looking for? Or was she actually his mother from the future pregnant with him or something? Anyway, we'll never see him again!
It was funny how quickly they just dumped Dan because they had nothing for him. The scene with John Bishop and Bradley Walsh together made me appreciate that Walsh is actually a decent actor whereas John Bishop is just...John Bishop.
Wasn't it really heavily hinted in the previous episode that Yaz and the Doctor were in love? That seemed downloaded here.
PREDICTION: The last line of tonight's episode is "What? WHAT?"
To be fair this was easy to predict (and I was one "what?" out.)
