I have agreed with you about that my entire life.
But I first saw this film unintentionally, by accident.
Remember double features?
By way of background, I am a lifelong fan of science fiction novels generally, with a special fascination with the 'time travel' theme. That year a film arrived that was 'must see' for me--- not this one --- The Final Countdown. To my surprise, it was a double bill day and the other film was--- You guessed it.
Twenty Five years later, my wife and I actually visited the Grand Hotel and Mackinac Island, a fascinating place even had the film never existed, not on SIT weekend. It was a memorable trip for me and that hotel is awesome. Worth the trip for that alone.
I love The Final Countdown too! Great movie, IMHO. Great soundtrack too.
Then you have read Diana Gabaldon’ Outlander series?
