And again...
This is why all the Marvel vs. DC fanboy nonsense is nonsense.
This is Hollywood. These folks aren't fighting a war. Why should we?
Because you can't like more than one thing at once. It's like having an Xbox and a Playstation, or even a Switch, and liking all of them! Who does that?
Being serious now, on the plus side this worked out superbly for Gunn. On the minus side Suicide Squad is 2021 IIRC so this GoTG 3 is likely a 2022 movie. 2 years after it was supposed to come out. On the plus side again he can tweak the script for some of the Fox characters. Maybe introduction of Silver Surfer and Galactus.
