From "The Day the Earth Stood Still" to "War of the Worlds" and all the similar attempts to portray alien visitors to our world, the wonder of this genre will continue unabated.
"ET" appealed to the wonder in all of us for things out there. "Ghost" spoke to the hope we all have for life after death, the concomitant desire that love conquers all and that sinners ultimately pay.
Any message intended by "Close Encounters of the Third Kind" was unfulfilled in the wonderment and wizardry of the overpowering special effects. The portrayal of extraterrestrials in movies and television has either been the evil invaders or the mysterious entities, too esoteric for us to interface with.
Envision in your mind such repeat visitors that are real, with definite purpose, who reach out to Earth's common man and woman in fulfilling that purpose. By so doing, such a visit would be similar to that of an intelligent mankind's visit to other worlds. Envision such a purpose that regales the heart in explaining the soul and its possibilities, when corporeal life is no more.
Such a story is "Journey III: Return to Earth."
"Journey III" set in the world events of 1980 will appeal to the Everyman's dream-the dream to participate in the adventure and hope that lives in each of us.
