Whether we favor or oppose impeaching President Donald Trump, we think that people who disagree with us are destroying our country. These days, many of us feel anger, fear or even hatred toward people different from us. The good guys, by contrast, have faces and back stories that the audience can relate to. They wear identical full-face helmets that erase any sense of humanity or individuality. Neither Darth Vader, the main antagonist in the first trilogy, nor his storm trooper enforcers have faces. The evil characters in “Star Wars” are generally one-dimensional villains that everyone loves to hate. But the stories we tell don’t just reflect our world. When we go to a sci-fi movie, most of us see it as entertainment, not citizenship. The latest episode in the long-running “Star Wars” series is a popular choice for holiday movie viewing.
