They are some how juggling it well, but I already think the MCU is getting a little too big. I'm excited for Infinity War but I don't see how it's going to tell a cohesive story with that many characters and that much shit going on. The Russo Bros. successfully pulled off a large ensemble cast with Civil War, but Infinity War seems like Civil War x10.

Now merging with Fox and adding the X-men to that? TOO MUCH.

Aside from the fact that without Wolverine the current X-Men roster is pretty boring. And there's the whole problem with Quicksilver.
