I did.
Okay, so the main antagonist thingy is defeated. Great. That only happens in every movie ever.
I don't read the comics so I wouldn't really know or care.
Nick Fury being in hiding isn't even a big deal, probably. I'm guessing he'll probably still be just as involved as ever in future movies, except now they'll have one-liners written for how he's in hiding.
so because you don't read comics, the plot isn't important? I don't read comics either, but I still saw the importance of this movie
S.H.I.E.L.D. is no more, this changes everything within the MCU
These movies take place in their own movie universe based loosely on comics, anything could happen. In fact, I don't even know if SHIELD ever dismantled like this in the books, I doubt they have.
