Trouble is the movies have had aos stuff in them with the guy from aos showing up in cap 2. (so there has been someone from the show in the mcu films) and the agents helicarrier from the show showing up in avengers 2 plus Jarvis in endgame there had been crossovers. Plus aos told us where abomination was something the movies never did and had nick fury, maria hill and sif show up. So there have been aos stuff in the movies plus a full character showing up.The whole notion that the shows, especially Agents of SHIELD, didn't take place in the MCU has always struck me as not just foolish, but overly complicated. So what, the AoS universe is exactly like the MCU with all the same events happening at the same time, and all the same characters (played by the same actors), except Coulson's alive? That's far more complicated than it needs to be.
