Do good ideas in superhero movies and television change people's philosophy?

I have really enjoyed the pro-freedom and pro-personal responsibility messages of some recent superhero movies. However, I wonder whether those messages do any good. Rationally, I believe that a person can enjoy these superhero characters and then relate their qualities to a normal human standard. However, for the average viewer, I wonder whether the gulf between their superpowers and ordinary human powers creates a moral gulf too, so that people see the moral ideals of the superheroes as beyond the reach of us mere mortals. Is that right? Can these movies really affect people's ideas?
