My wife brought up a point that its interesting to watch a movie where the means of communication are more limited to what we have today. Many movies in the early 90’s and earlier don’t have cell phones and the Internet was still mostly a governmental entity. The World Wide Web was still being developed, Facebook, Twitter and Blogging did not exist. So characters in movies and TV communicate by talking in person and by phone.
Friends who are of a certain age don’t understand so its like taking a trip back in time. I would say watch movies before 1994 to see a time before modern tech takes off.
