This really does feel like the time between TTT and ROTK. Where you just know that an adapted literary story is being translated to the big screen with possibly the absolute ideal director/writer team for that particular project. How lucky that we've gotten multiple perfect storms of talent and subject matter throughout our lives. The OT, LOTR, and now MCU.
Even *if* IW2 is somehow a bloated mess you just know that there's going to be any number of individual payoffs (return of ashen heroes, Cap getting his proper shield, Hulk's revenge, Thor's revenge, probably at least one show-stopping tracking shot of all 25+ heroes fighting in the same battle, etc.) that will be more than worth the price of admission.
One theory I have (that I'm sure others have come up with on their own) is that Red Skull was only "cursed" to guide others to the Soul Stone simply due to the fact that he has nothing to sacrifice since he has nothing that he loves. So he deliberately waited for decades for someone to come along who *could* make the sacrifice and get the stone so that he can steal it out from under them. I really wonder if he'll be hiding in the wings to reappear in IW2.
That aren't in any way connected to each other (because it's just so hard, lol) and that will probably be reshot by another director halfway through.
