I guess the problem is that most people watch SciFi movies for the adventures, the anticipation of the future, the special effects, etc., not the knee jerk concessions of minor Hollywood stars to current societal concerns. There is a place and maybe a need for exploration of the evolution of social mores in movies, and thoughtful, watchable films have been made about these subjects. But mostly not in Hollywood, and certainly not within SciFi and superhero franchises. Frankly, if one has superpowers like a Jedi or Captain Marvel, agonising over one’s sexuality or love life seems so far out of character it could as well be happing in another galaxy.
