...To be honest, I would rather see the Shannon family wake up in 2149 and find themselves getting ready to enter the orbit of an earth-like planet somewhere in our solar system. Later, when listening through archived communications from earth, they discover that human life on earth was probably destroyed by a massive meteor strike. The future of the human race is completely dependent on the colony.
The colony winds-up landing on a planet that resembles prehistoric Earth. The show follows the Shannon family as they struggle to build their new home and populate the planet...and do it right this time. Of course, the irony is that the colony must "be fruitful and multiply" (Genesis 1:28) for the human polulation to survive and somehow strike a balance once someone determines there are enough humans consuming enough resources on the planet. Good luck with this one! The viewers certainly aren't going to stick around a thousands years for this crisis to develop. I'm just having trouble imagining how this show is going to keep me interested more than a few episodes. We shall see...
It's been basically done, several times. It was called: "Swiss family Robinson".
