My main problem with the DC movies is that they understand that "audiences like The Avengers, ergo Justice League movies = profit", but they don't realize the reason why audiences like the Marvel movies.
It's not because of the big crossover events, it's because of how it builds up to the crossovers. The way the drop hints to the next movie, the little easter eggs they leave for devoted fanboys, the way that the movies were structured. It's the way that they buildup the characters - in some ways, they do it better than the actual comics (Civil War the comic was awful, but Civil War the movie was great). It's the way that they put lesser-known properties on equal footing with the big names.
But DC just thinks "okay, we made the Superman movie, now let's have him fight Batman!" But the Nolan movies ended on a pretty conclusive note, how can we get out of that? "Let's just reboot Batman again!" But we already know his origin story. "He's been fighting crime for a long time! In fact, he's coming out of retirement!" Do we see any of this in the movie? "Nah, but let's pretend we already shown it!" Okay, what else? "Let's start forming the Justice League!" Do we know anything about the other people in the Justice League? "No, but let's have a montage where they show off their powers!" Okay, you also said that Wonder Woman's going to be in it. Any idea what she'll do? "Just show up near the end". That's fucking stupid. So, what else is there? "Well, Doomsday's in it, and we'll also have Superman's death and resurrection, and also Darkseid, and a time-traveling Flash, and -"
Okay, you just burned through about six movies worth of good material. What the fuck are you going to do now? "Uh...count my money?"
Yeah, good luck with that, strawman DC executive. The 69% box office drop-off says otherwise
(Oh, and on another note: The superhero-crazy Chinese market hated Batman v Superman. The second-week box office drop-off was 82%. One Chinese viewer described the film as being "true abuse from beginning to end...bloated, sluggish, and clumsy, like a stroke victim")
