Doctor Who new year special revolution of the Daleks

Well on new years day we had the new 2021 Doctor who special (always used to be Christmas day) This ones called revolution of the daleks. Now I made a point of watching it and watching it carefully. This was to actually watch the acting. First of all it wasn't terrible, the story is an American businessman steals a knackered dalek. This enables him to make security/police drone copies, with two guns instead of the sucker. (If this sound familar it's the basic plot of terminator and skynet) Anyway unknown to the businessman one of his tech nerds has been cloning the daleks and they intend to take over the new housing made by this blokes company. It also has a return of Captain Jack Harkness, played by John Barrowman. All good so far. Now enter the Doctor and it all starts to unravel. You see with the best will in the world Jodie just cant be convincing as the doctor, shes easily the weakest actor in the cast, even the tech nerd easily out-acts her, and he's a bit part player not a lead cast. It's just silly. Trouble is the news gets worse, two of the cast left the series, Ryan Sinclair played by Tosin Cole one of the better actors and much worse Graham O'Brian played by Bradly Walsh, the best actor in the show! This leaves the Doctor and Yasmin Kahn played by Mandip Gill, one of the weakest after the Doctor. This doesn't bode well for the future. The reason she had so many compannions was because she was so weak it took her off the screen, in this episode the doctors on screen for only about 35% of the episode, and this nearly always with other supporting actors to help carry her.
