Honestly, I don't get it. I could discuss Star Wars, or Game of THrones theories for days.
But even though I've seen every film in the MCU, and generally enjoyed most of them, nothing in me motivates me to speculate wildly about what will happen in this movie. I have tickets for Sunday, I'll see it then, and I'll probably just sit back and enjoy it.
Kevin Feige has worked a Hollywood miracle - creating a franchise that people love and shell out money for, but don't love enough to hate it when it goes their expectations.
