BTW the show's pilot was so off the mark from what was eventually created, it was never shown. It would be interesting to view as a historical curiosity.
It is very sad to see a comedy program break down with its discipline. We saw this with "The Monkees." "The Monkees" was a show that had potential to go longer and be bigger. It was ahead of its time. It drew nothing but puzzlement from the older end of the generation gap, those people who watched Lawrence Welk.
It took tremendous work and commitment to craft those 98 episodes. It spanned from September 26, 1964, to April 17, 1967. We remember the year 1967 as the absolute worst of the Viet Nam War. The show itself wouldn't have dared make a statement about that war. Apparently "Star Trek" did, on a subliminal level. I don't think there was anything subliminal about "Gilligan's Island."
The second and third seasons gave us 62 episodes. The show got solid ratings when it was current. But the popularity would grow in the years of re-runs following. Syndication in the '70s and '80s would make the show seem timeless, as firm a part of our culture as the Pledge of Allegiance.
