yes, but Marvel is very smart. They recognize a small weakness potentially in Black Panther. they have put him in Cap 3, and Civil War will probably partially see it's aftermath played out in the Black Panther movie, I think a year later.
they recognize even greater weaknesses in Captain Marvel and Inhumans.
But looking at the schedule, neither of those movies is gonna play out in a vacuum. basically gonna be Infinity 1.333 and Infinty 1.666.
I think Thanos is gonna be coming to Earth in Infinity 1. And the movie will end with him sacking Wakanda and claiming the last Infinity gem. and Earth's heroes will be devastated.
And overall, Thanos is gonna have a lot of Hitler/Sauron parallels. As far as how he's seen cosmically. Captain Marvel and Inhumans will take place, i believe partly on the same timeframe as Infinity 1. but both will actually spill directly from Infinity 1 to audiences. like in Infinity 1 Thanos goes around gathering gems and probably we'll see Guardians try to stop him and be beat, and introduce other cosmic figures like Adam Warlock and Pip, and Death, and Mar-vell.
Thanos storms onward, and heads to Earth to claim the last Infinity Gem.
end movie,
Captain Marvel will show the birth of Carol Danvers as Captain Marvel as Mar-Vell, desperately heads to Earth to warn the heroes there. So she'll have an origin born directly out of Infinity 1. and she will be intregal in going back out there, rallying up the remainder of forces left to fight him and heading for Earth. GOTG, Adam Warlock, Pip included.
end movie.
Inhumans will deal with the Twins starting out on a journey of discovery as to their true nature. during the middle of this, it will be shown that Thanos begins his invasion. but they will get to Wundagore, and be led to Attilan from there. and we will introduced to the Inhumans at this point. they will drive us there.
But the thrust of the movie will be the conflict of whether or not the Inhumans should go to Earth and help against this Thanos/Hitler/Sauron figure or remain neutral and hope for the best.
Maximus will be the real spear head of this conflict, rallying dissent against Black Bolt and saying that he's betryaing the Royal Family. Black Bolt will be unsure. The Twins will end up playing a part in his decision to cast the Inhuman's lot with Earth and they will commit to fighting Thanos.
maybe at this point, Captain Marvel and her coalition will show up to say, hey yeah, let's go. but then... movie ends.
Infinity 2...picks up exactly from where that left off.
Thanos sacks Wakanda, gets the last Infinity gem as this second cosmic wave of reinforcements arrive. second half of the movie is spent playing out the whole space/Death/gauntlet/battle arena of Infinity Gauntlet type thing.
and whatever somehow, he's robbed of possession.
so if they do it like that... just imagine how smart that is.
u are directly making two pretty weak properties way stronger by this kind of bookended introduction.
becuz GOTG was never a weak property it's C or D list in general audience recognition but that run they based the movie on is pure A+ list material and team character. Captain Marvel and Inhumans are definitely not that. and Marvel recognizes and they are actually moving realistically to try to make it impossible not to wanna see them anyways.
it's really smart stuff.
cuz GOTG is never gonna happen again. that was the only property that was that great, and also considered that small. u could make other things work, but GOTG was like the gold mine on that. nothing else even comes close to being that situation.
