I would argue that it is the opposite. People expect an info dump and everything explained to them. I remember watching Captain America: The Winter Soldier (I think it was the last movie I watched in theatre) and pretty much everything was explained to the audience. Guy Richie has character intro screens like Street Fighter in his movies.

Even in movies where everything is explained e.g. in Blade where they will have a scene where someone explains how a weapon works, I've noticed in a recent viewing of the movie that people forgot the explanations of the gadgets he has. In Blade they have a James Bond / Q like conversation between the characters to say "this weapons does X against vampires" and sets the weapon for later on in the movie and people forgot about it.

I watched "The Mothman Prophecies" and quite a lot of the movie was up to interpretation and there was many small things in the film that you might overlook e.g. there is a scene in a mirror where the reflection in the mirror is out of sync with his movements, suggesting something supernatural is occurring and he hasn't realised it yet. While I love the movie, there is very few movies like that.

If you watch movies before the 90s. A huge number of movies will have characters communicate efficiently and often realistically.
