Did DC just copy the Marvel Spiderman idea..
of bringing all the other batman's and superman's back (from other timelines, actors from our past that played batman and superman before)
I was amazed at the elegance when Marvel first did it in Spiderman - No way home (where they brought the old spidermans and old actors and old adversaries back, explaining it with the multiverses)
Now i felt i had already seen that again and was like 'again?')
