I walked into this frightened that there would be too man characters and the result would be an empty vacant shell of a movie that was pulled in so many different directions it couldn't make sense of itself.
Yay, I was wrong.
Seriously, they did a good enough job. They focused on Gomorrah, Thor, and Strange and Stark enough to make a plot despite the insane amount of characters. And the rest they used as filler, with only the Vision story coming up a bit light due to population.
And the Vision story was a bit of a draw back. It was there but it wasn't, but at least it was there, it was... read the rest.
