This is my main worry: now, Gunn said the lineup would change for GotG 3 but man they need to stick with this for the story to have any meaning. Obviously the end is a cliffhanger: you can't kill Black Panther after his film hit the third highest domestic gross in box office history, but Gamora needs to be the sacrifice.
I thought that IW was pure insanity, it mostly acts as a teardown of everything that was built up... sort-of as it's meant to be. The 'arcs' that are focused on are quite unexpected, outside of Thanos and Gamora of course. I guess in that case I shouldn't be surprised that this was basically half a Guardians of the Galaxy film (who supply some much needed levity in places, Drax in particular)... but Vision/Scarlett Witch over Captain America? Yeah he has a stone but man you kind of felt cheated. Even Tony didn't get as much, despite his isolation on Titan and caring for Peter. Of course, I have to imagine this will all come into play with A4... but IW is both what we wanted and yet what we didn't at the same time. I'm just amazed on how breakneck it is, and the ability to be both completely satisfying and not at the same time.
The reward is on the audience for watching every single film. Yet it makes it completely difficult to separate this from anything. At all. There's not a standalone feel from this, even if we were to wait til 2019. Thanos appears right away like a freight train slamming into the deliriously goofy ending of Thor Ragnarok, as if our Netflix just automatically played the next "episode". And yes,
this is how the film is designed, and I'm not faulting for that... I'm just surprised how the Russos absolutely refuse to play into cinema convention for newbies. I can't imagine taking a MCU newbie to this, I'd feel incredibly sorry for that person. That's the only thing making me take pause at IW, because for what it's trying to do, it almost nails it... unpredictable, but delivers the goods nonetheless. What a wonderful, intense cliffhanger ending. Either way, I can't wait for 2019.

@Nick I believe Ant Man and Wasp takes place before IW at least, as IW only takes place within at the very least three or four days. I can't see them dealing with half of mankind just suddenly vanishing.
