Ones with overt social agendas that feel out of place. If you want to make a movie solely about that, fine. Yet, when they try to disguise it as something else, it takes away from the story-telling, and brings you back to reality. Movies should be an escape from reality.
Disney is bad at this, and though I don't hate the movies (still like them, but they aare guilty of this) some examples include..
Beauty and the Beast (live-action)
Star Wars: The Last Jedi
