Except that my, admittedly unnuanced, summary of "the producers' ideas" is how Mirror Georgiou is portrayed up until the last episodes. Sure, there are moments where she is almost kind to Michael, but to most everyone else she is mean, condescending, and she is definitely willing to kill at a drop of a hat. To me, Terra Firma p1/p2 feels like a last second retcon. An attempt by the writers to say "see, Georgiou did make great strides in changing and improving her understanding during her time in the Prime Universe". But, like a lot of what the Discovery writers/producers attempt for these characters in terms of emotional arcs and 'earning' things, it is rushed and paper thin. [I am blanking on a good example right now, but there are many attempted character arcs in Discovery where the characters arrive at their end point seemingly by writer fiat - "they 'evolved' because we say so". The thought to have said character development is there, but the season-long story arcs and the divvying up of writing assignments between the writing staff just don't allow enough development time, consistent trajectory, or sufficient payoff. Again, in my opinion.] As soon as Georgiou is gone, the whole senior staff has a grand sendoff where she is treated like a hero and great friend to all, where she had previously been mean, murderous, disdainful, and hateful.
