If you are expecting to see dinosaurs straight away when Steven Spielberg's latest big-budget TV show starts this weekend, you will just have to be patient.
It takes a little while for the family-friendly, time-travelling dinosaur adventure series to go back 85 million years in time to the Cretaceous period. But when they do arrive there are some nasty - and nice - dinos ready to feast on any human they can get their gnashing teeth into.
The feature-length pilot starts in the year 2149 when the world is a dirty, stinking, overpopulated place. The only hope of survival is fleeing this Blade Runner-like land and sending people back through a time portal to Terra Nova, a prehistoric colony that has been set up to give the human race a second chance at life.
The central question Spielberg and his team want the show to address is: If humans were given a second chance to start over, would they make the same mistakes?
First, we meet policeman Jim Shannon who is imprisoned for assaulting an officer who found out that he and his wife, Elisabeth, have had a third child when families are restricted to two. While he is serving his sentence, Elisabeth and their teenage children (but not youngest daughter Zoe) are recruited for the Tenth Pilgrimage to Terra Nova.
