Primer had the problem for me if I recall correctly, which is a shame because the movie's heaps of expository dialogue. It's a
noticeable trend that's had an uptick in the past decade or so. The degree to which it affects you is case-by-case but I've found it with a lot of films in the past few years, and so have others.
Also 'Mid-Atlantic' is more common but the terms are synonymous.
