A lot of people keep complaining about 2 different batmen. I really wanted Battinson to be in DCU, but I thought for a while and I feel its best if he's kept separated, and I'll explain why:
Avoiding the unplanned chaos: We all know the mess DCEU was. Man of Steel was never supposed to kick-off the DCEU, unlike Iron Man did. Similarly, Matt Reeves's Batman isn't supposed to be a part of a bigger universe.
Creative freedom: Gunn already stated that he wishes to respect Reeves's standalone universe. Batman came at a chaotic time when the DCEU was already dead. It's best to not force it into another universe, and make Reeves face the same tragedy that Snyder did.
The antidote for the MCU issue: One of the biggest issues MCU (I love MCU, I'm not the Marvel vs DC guy for the record) created is that people prioritize the actor over the character. They can't see anyone else playing Iron Man or Captain America. DC should go the other way: a lot of people can play Batman because there are a lot of interpretations of the character and a lot more stories to tell.
Elseworlds Rising: A lot more stories means a lot more elseworlds movies, which is an indispensable part of DC. The biggest difference between Marvel and DC is that the best storylines in DC are one-shots like The Killing Joke instead of a crossover (I do love Final Crisis though).
Let's hear your opinions fellas, what do y'all think?
