I'm not calling Gunn names, I was just saying I don't like how he says/tweets/posts there won't be a crossover between the two franchises, because at the end of the day that's not up to him. I like him and enjoy his movies, but it came off somewhat defiant to me the way he posted it. Like no way that's happening. Again, NOT his call.
I'm interested in how the two parts play out. I think one leans toward Earth-bound, and the other will be comsic-bound. One part will have half/certain characters in it, like when they said certain Avengers would miss Part 1 but return for Part 2.
It could even be a situation where there is a fight in space above Earth, because I feel humans need to know its going on and make it real for them. To have the Avengers save Earth and no one really sees it or knows about it wouldn't make sense to me. They need to make it "real" to those on Earth in some way.
