Zack Snyder's Justice League just landed on HBO Max, and though it's not considered canon by Warner Bros., that isn't stopping Snyder from detailing what could've been. This movie would've been just the first in a trilogy, which would've seen the deaths of several characters, and at the end, a new Batman taking up the mantle of the Dark Knight. In fact, it would've been Superman's son that dons the cape and cowl. What do you think of this? Let us know in the comments!
