They should remake this movie or do it as a multi-part season on HBO or Showtime

Original book ending?

Or MOVIE ending?

The book ending had Francis secretly helping kill other Sandmen so Logan and Jessica could escape to the surface only to find a nuclear wasteland and a spaceship that takes them to Sanctuary...on Mars.

They'd have to seriously work the underlying theme. The story was written during the days of the "generation gap" and "never trust anyone over thirty", when a hell of a lot of people were feeling irrelevant or out of touch if they weren't young and with it.

It could make an excellent show if they find a way to relate it to the modern world, either making it about helicopter parents or their spoiled offspring, or the SJW nitwits on modern college campuses. Or a satirical look at a society based on young people who never look up from their smartphones. Whatever annoys the mainstream the most.
