All mainstream modern mass media TV, movie, novel narratives are politically correct - but there are two ways of being PC - and one is a lot worse than the other.
Some modern stories give the impression of having been conceived independently, then politically correct elements were secondarily added in order to to throw a bone to the Thought Police. This is what the Social Justice Warriors accurately call 'tokenism' - e.g. casting a woman or racial minority actor in the role of high status character such as a judge or the president, but without this affecting the motivations, plot or action.
While tokenism is annoying and diminishing to a creative work, and is a constant reminder of the power and dominance of the New Left, it can be tolerated - and 'bracketed-out'.
But what is intolerable is the opposite - when the storyline is PC propaganda, and the narrative integrity is token. When the whole 'point' of it is political propaganda, and the story is simply a manipulative tool to try and make the ideology effective and memorable.
An example is the ongoing Doctor Who episode The Zygon Invasion, scripted by Peter Harness; which is a pro-mass-immigration political allegory - crudely dressed-up as a Doctor Who episode.
I could not last-out the whole episode once I recognised what was going-on (which did not take long!) but it is an example of the very worst kind of Soviet style propaganda at almost every level - but given a high production gloss.
So we have strong preaching of pacifism/ willing victim status in line with the author being Peter Harness who wrote Kill The Moon last year - which was (by a large margin) the Worst-Doctor-Who-Episode-Ever (therefore naturally he was paid to write more on the same lines).
We have not just a female-led, but apparently all-female UNIT - which is there to show us how the military ought to be done.
(i.e. spending most of the time gossipping about the doings of the 'alpha male", sharing personal feelings and sympathizing for personal feelings, disobeying orders, breaking down and crying - and, in general, failing to use just force to defend the Good.)
Indeed it has become common in this incarnation to have the screen mostly filled either with the Doctor surrounded by women and minorities (and minority women) - or else just have the women and minorities dominating the plot, and the Doctor absent.
Doctor Who in the post-revival form has been heavy on tokenism - with far too much emphasis on the Companion (and even the Companion's family, for goodness sakes!) - in a crude, and successful, attempt to woo a female audience by turning Scifi into Soap.
(Some of the Rose and later Donna episodes closely resembled the egregious East Enders - which is a very popular and long-running soap about a collection of vile Cockney harridans, sluts and thugs meant to be 'ordinary people'.)
But the new Doctor has been crossing the line from tokenism into propaganda; and crossing the line between something I can just about accept, into something that I cannot bear at any price. With David Tennant we had the Doctor as a superhero (rather than a wizard).
But now with Capaldi we are getting Clara as the leader, and the Doctor as a cowardly and pathetic middle-aged sidekick . A Platonic sugar daddy to his beloved Clara; in seventies style Ray Bans and Electric guitar (posing like a superannuated rockstar 'ambassador' such as Bono - making peace signs on the stairway of his private 'World Presidential' jet).
And when action is needed the Doctor behaves like a dependent wimp; texting Clara for help more than a hundred times! She casually shrugs off this appeal until it is convenient for her to answer - clearly establishing 'who wears the trousers' in this 'marriage' - and characterizing the Doctor as an weird internet stalker.
So, expicitly and with emphasis, we now have a Doctor who cannot even start doing anything to solve a crisis without the go-ahead from his strong, fearless, beatifully dressed, and utterly dominant younger girlfriend... I mean Companion.
So even the basic character of the Doctor, as signalled by his clinging and insecure relatonship with the Companion, has been subverted and sacrificed and forced into service as political propaganda; teaching us how men and women ought to relate in the coming Leftist utopia of willed and embraced 'alien' invasion and takeover...
In conclusion, I can tolerate tokenism up to a point, which is just as well because it is now universal; but when I am offered crude allegorical propaganda for self-hatred and willed-suicide, dressed up as drama, then I switch-off or walk away - and I do not return.
