Everyone's entitled to thier opinion.
They hyped the crap out of "The Death of Superman" same with "Knightfall". After reading those I never said "oh man, they might kill Batman next, mebbe even Wonder Woman( even though they did later 😉)".
The only three comics that ever made me say "man, who's going down next?" were Aquaman's "death" in Our Worlds at War , Firestorm's death during Identity Crisis, and when Wonder Man blew himself up real good in Force Works.
Funny thing is, all three of these characters were revived--Aquaman and Firestorm less than two years after they bought the farm. The new Firestorm's sales are flagging so DC has already allowed Ronnie to reappear (albeit bodiless) in that comic. These guys are like MC Peepants! 🤣 🤣
Someone would have to be crazy to think that DC would permanently kill off one of their "big three"--even after Superman "died". Only B-listers and sidekicks aren't safe in the DCU, and then even they will eventually be brought back (look at Hal Jordan and Metamorpho--even Donna Troy is going to come back).
Having a hero die only to bring them back 1-5 years later only cheapens their sacrifice, it doesn't make people care about the characters more IMO.
Only two times has a hero come back in a way that didn't cheapen their death: Hal Jordan and Colossus. That's it.
The only superhero deaths that I respect are Barry Allen, Colossus,Phoenix (the first time)Synch (who really shouldn't have died), and Hawkeye's (so far).
A major death is planned for DC's new Crisis (my money's on Kyle Rayner, Nightwing, POSSIBLY Martian Manhunter). We'll see how long they stay dead.
