This is not really Old School Sci Fi but perha…

This is not really Old School Sci Fi but perhaps it does in some vague and peripheral sense relate to same.

Next year’s Marvel movie “Captain Marvel” (2019) starring Academy Award-winning (as well as Golden Globe, Screen Actors Guild, and British Academy Film Award-winning) actress Brie Larson is being described in the media as a “period piece” because it is set in the 1990s.

I can perhaps see “Captain America: The First Avenger” (2011) starring Chris Evans being described as a period piece since it was mostly set in the 1940s, nearly 70 years before the film’s release date and depicting a world that was technologically and sociopolitically very different from the early 21st century, comic book origin story trappings aside.

In the case of “Captain Marvel,” are the 1990s now far enough in the past that a movie set during that time can be regarded as a period piece?

To put it in another context, the original “Back to the Future” (1985) is set in both 1955 and 1985. Depending on how early or late in the 90s “Captain Marvel” is set, the film will have a somewhat shorter span of years separating the era depicted from the year of the movie’s release, however the 1955 and then-present 1985 of “Back to the Future” are on opposite sides of the tumultuous 1960s during which time American society underwent atypically radical change in a comparatively short time. As Vladimir Lenin is said to have remarked, “There are decades where nothing happens; and there are weeks where decades happen.”

Did America’s (and much of the world’s) transformation from a Late-Industrial/Cold War Society to a Post-Industrial/Post-Cold War Service and Information Society during the 90s constitute enough of a change so that the pre-World Wide Web and smartphone early-to-mid 1990s are now more “distant” in an historical sense than the mere number of intervening years would suggest?

Just curious.
