SERIES PREMIERE: Think of this new reality show as something far removed from reality, but still potentially interesting. It’s like Big Brother, except the participants in this particular contest are divided into two abutting, very different fantasy worlds: one from the primitive past, the other from the shiny future. It’s based on a hit reality series from Chile, and actually seems like a good fit for Syfy. Which is more than you can say for, say, WWE SmackDown.
