Just watched it. It was very good. Easily the best Marvel movie yet. To weave 11 years and 20 movies together like they did... all of the callbacks to previous events and characters
Half the audience clapped when Cap got the hammer.
The Captain Marvel super-push seems very forced, thankfully she wasn't in this movie much. I don't care for Carol Danvers.
I have two theories about what sounded like metal clanking together at the end... someone building a new "heart" for Tony (we never did see what they did with his body) OR.... the more interesting option: Doom making his armor
Phase 4 will be Fantastic.
