New DCU Plans
I can't think of a single person I know who even knew who Blue Beetle was, for most normies, comic book knowledge doesn't travel much past the A-listers. DC, its Batman, Superman and Wonderwoman. I wouldn't even consider Flash one, even though there have been plenty of media about the character. I just think you need to get normies(non comic book ppl) to get excited. The Flash was just never interesting to me, was never going to see the movie regardless if they dumped Erza or not.
The MCU was always able to tie to a bigger arc, so normies who were invested in Ironman, Hulk, Cap, Thor, etc. Antman would never stood on its own if it wasn't tied to bigger stories and by the time Antman came out, you had a base of normies who were already invested, much like a soap opera. I thought Captain Marvel was a horrendous movie but the reason it did fairly well was because it was the 1st movie after the snap and everyone knew the post credit scene was gonna show off something. Many normies didn't read the Infinity Gauntlet series where Thanos snapped, so the end of Infinity War left a lot of those people speechless and were itching to see what happened next.
