Except, that’s the thing: it DOES make sense at Marvel. That’s one of the things Marvel touts and that the readers enjoy. And that’s not to say they don’t retcon things, because they do, but those retcons usually come in the context of the larger mythology that goes back to the original stories from the 60s. DC used to do the same thing (and still kinda does with Rebirth) and it worked for DC too.
Regardless of whether you think it’s something that you wanna invest in, it actually works. That can’t be argued against. We see it work for them. And again, it’s constantly used as a “reason” for why Marvel is “better” than DC. So, yeah, rebooting is hurting DC more in the long run than helping it.
