For many “fans,” it seems like it’s trendy to be cynical and negative.
They can’t just enjoy a new Trek, or Star Wars, or Marvel movie, without picking it apart and finding everything to complain about - and then criticizing not only the show/movie, but the more positive fans who are willing to overlook such trivial issues and just have fun.
Not to mention the really awful subgroups of fans who will hate any genre where a woman hero or a minority hero gets time in the spotlight. They tank viewer ratings, harass the stars on social media, just go out of their way to ruin it for everyone. Totally toxic.
