Episode 8 was subversive because it had self aware moments "trolling" the audience throughout like Luke mocking the idea Rey (and the audience) thought he would pick up a lightsaber again.
It also has weird "subversive" dialogue about sacrifice being bad that doesn't really fit what's happening in the movie itself where sacrifice of two characters saves the day. Which is "subversive" in the sense that a movie with dialogue saying "this is a shitty movie plot" is subversive.
It also rips off the ending of Return of the Jedi by killing the main bad guy so is "subversive" in that it trolls whoever was stuck making episode 9 without a functional villain.
