None of us should be that surprised by this news but it's still a bummer nevertheless. The Marvel Cinematic Universe is huge that now has almost $12 billion dollars worldwide box office and television shows across four networks. The world of the movies is starting to feel just as big and expansive as the world of the comics. Well, almost anyway. There is still this huge brick wall between the movies and television shows. While the movies have been effecting the television shows the shows have not even been acknowledged in the movies. There is a good chance that the Avengers still don't know that #CoulsonLives.
It's been a little frustrating for fans of the television shows as they see the characters they loved routinely ignored by the movies. It's something that fans were hoping would be solved in the upcoming Avengers: Infinity War or Avengers 4 even if it was just a blink and you miss it scene of the Agents of S.H.I.E.L.D. or The Defenders fighting in the streets. There really isn't any reason there couldn't be a crossover aside from logistics. Marvel mega-producer Kevin Feige was asked about these possible crossovers in a facebook Q&A with French site Allocine (via ScreenGeek) and it doesn't sound promising.
"Maybe someday. No plans right now. Maybe someday, but we have a lot of characters in the MCU, and one of the things that is so special about those characters on the Netflix shows is their dynamic together. They are all combining to become The Defenders later this year and are doing their own thing."
This is the same answer we've gotten for years and it doesn't look like it's going to change anytime soon. For a long time fans thought that Marvel was just ignoring Agents of S.H.I.E.L.D. because it was only sort of good but the Netflix series have been pretty consistent. The actors want to make the jump but the people in charge don't seem even a little interested. Aside from incidental details Marvel TV and Marvel Movies are becoming their own separate universes. If they aren't going to crossover then why continue to say they are connected at all? It makes more plot holes than it solves and it disappoints fans.
