In comics, DC is crushing it right now. I was a Marvel Zombie for most of my comic reading life, but the past few years caused me to drop almost everything Marvel. DC, however, has greatly excited me.
Now in the movies... maybe people are just sick of Batman and Superman? People loved Wonder Woman and I suspect they’d gobble up an Aquaman movie. But we’ve seen so many reboots and iterations of Bats and Supes (including on TV shows airing at the same time as the movies) that it’s harder for people to be excited. I think they want something different.
