The Space Between Us is a 2017 movie that I do NOT recommend as it is heartbreakingly depressing.
It’s the story of a boy who is born and raised on Mars whose heart (larger) and muscles (weaker) are adjusted to life on Mars but not on Earth. He takes a trip to Earth to find his father and the girl he has fallen in love with via cyber chat. But he can’t survive for long on the Earth, and in the end, he has to return to Mars. “Home Sweet Home” say the boy and his father overlooking the barren red Martian landscape at movie’s end. The sentiment is fake and it is obvious.
But the premise of the movie is stupid. “If we had to, mankind could make a fresh start {on Mars}. We’re in trouble and it’s our fault. … Mars is a planet ripe and ready for life.” We have made such a mess here on Earth that we need a backup plan, a Plan B, and Mars is it. So, they begin to colonize Mars, 6-8 Earthlings at a time.
