I'm a astrophysics geek so details in sci fi programmes are uber important. But remembering the adventures of Robinson Crusoe....i think the writers wanted to keep things as light as possible. It's no west world and even star trek got loads of things inaccurate. It's an easy weekend entertainment to binge on....toby is cute, dr. Smith and the Argentinean guy are not bad either. The kids aren't even annoying
