A good sense of an on-going movieverse continuity:
Fury returning from retirement;
Banner missing at the end;
some team members leaving;
other superheroes joining.
Not being a Marvel fan, I had to google the Vision. I am not sure why Ultron had to become destructive except that that is what Frankenstein monsters do. A fight scene near the end reproduced the look of the Ultimates fold-out. Good to see the Avengers partying and also to see thanks to comics creators in the end credits.
