I think your view of a particular time period as a JW, depends on where you are in your life and what you've already experienced. With the advent of the JW dot Org Website, JW TV and shortened meetings etc, people of a certain age are feeling the same way today about being a JW as you were back in the 80's when they came out with videos and cassette recordings etc. As it was back in the day all the evidence is there, yet a certain amount of those involved today who are at just the right juncture in their lives, think everything is new and exciting and still think they are on the right track.
To me after living through the 1975 hype, there was a sense in the 80's of "hey....weren't we supposed to be in the "New System" by now....who wants to read all these new books that explain the same old thing....a thing that never happened?
I think back in the 80's, newer or younger ones likely felt the way you described, because they were projecting their own feelings onto the experience, the way we all do.
