No spoilers. I saw Avengers Age of Ultron and apparently no one in the theater I was in understood the movie. For example afterward I heard one mom ask her kids who one character was and they said "Phantasim." I'm not even sure where they got that name.
While in the theater the movie was in the middle of explaining the same character when I heard a little kid repeatedly ask who that was. Things like this just amuse me. I sat with a great audience that had some good reactions to the movie. I actually heard people gasping in surprise during one reveal. I didn't stay for after credits because Whedon said there would be no after credits scene. Although there is a short one a few minutes in.
