Take the two most popular Trek movies in general. TWOK is a thirty year old movie. TVH is over twenty-five. When I paid money to see them in the theater when they were released, I walked out feeling thoroughly entertained. My friends and I would talk about the good and bad parts, then decide when we could get together to see them again.
Now, when I watch TWOK for maybe the twentieth time, parts can get tiresome. Heck, I'm thirty years older, too, and I'm bringing a different perspective to the movie every time I view it. Few things ever become timeless. That TWOK or TVH still provides any enetertainment value at all is probably amazing.
All I know is TWOK and TVH, flaws and all, have stood the test of time better than a lot of the music I listened to in the early and mid-1980s. "Classic Rock" my ass.
