This video mentions Nineteen Eighty-Four as an example of Dystopia being inescapable…
But Nineteen Eighty-Four ends with an Appendix. An Appendix that was written from the perspective of a time after Oceania fell.
The heroes may not have won in Nineteen Eighty-Four, but taking the message that a true Dystopia can never be broken is, I think, both against the text that they are referring to, as well as the author’s apparent intent.
