Wife and I just got out. Incredible ending to this phase of the MCU.
When all the portals opened and the finale started, I thought, "Yea, this is how this should end." Absolutely awesome.
My only concern is, where to now? I really don't want them to turn the MCU into Star Wars (revolving around space exploration, save that for getting the Fantastic Four). Not to mention, whose the next climatic villain? If I had to guess, maybe an Apocalypse or Onslaught scenario done right with mutants joining the frey? If they do go space, maybe Annihilation?
Wife was asking about why they are just getting rid of Black Widow and Iron Man, and it brings up a good point. Are these actors/roles so ingrained that we'd rather remove them from the MCU instead of recasting them? I mean, Cap is a bit easy (with the comic progression to Sam Wilson or Bucky Barnes). But are there enough popular characters for people to be excited about new MCU movies unless it's the most die-hard of fans? I guess if you can introduce Carol Danvers and make a mint, you can do it with about anyone.
Anyway, epic. So epic. I'm literally starting up watching the entire MCU from start to finish again just so when Endgame comes out on DVD, I can be ready.
