First of all, Hollywood does occasionally sanitize films and TV shows. For example, the suicide scene was removed from "13 Reasons Why" after concerns from mental health experts that it might inspire copycats [1].

But even ignoring that, I think most people have a good understanding of what a movie is and that fictional characters are not real. Movies have been around for a long time, most people have been watching them their entire lives. I don't think at this point that most people have nearly as good an understanding of chatbots. If you can converse with one and it mostly delivers responses like a person would, some people will start treating it like a person and ascribe values to its statements, and that's where it potentially gets dangerous.
