Superhero fans are diverse bunch - look at the nerds in that AV Club article's comments section; they
hate Snyder.
And Borstalboy, the same stories happen over and ****ing over in tentpole superhero movies because a $400 million budget makes studios even more risk-averse than they usually are. Also,
this. Actual comics tell the stories of, oh, cops enforcing the law in a world where eating chicken is outlawed. A PI pastiche starring a floating amoeba thing. The last man on earth and his pet monkey going on an epic road trip with a government agent and a cranky geneticist after every other mammal with a Y chromosome suddenly dies.
Some people - a small but loud group - are "superhero fans" in the sense that the success of anything with the Superman logo stamped on it feels like a success for them - it's part of their identity, so they're the ones giving rave "reviews" before they even see the movie. Other people aren't paying much attention and will just watch this movie opening weekend because they want something to do and this film has the names of two pop culture icons in the title. What will be telling is not the first weekend, but whether this turd has any staying power. Even by tentpole standards, this movie was expensive as hell.
