IGN - Now that's more like it. After last week's procedural drama, it's good to see Terra Nova switch gears and deliver a suspenseful action-thriller with a big development for the Sixers storyline. "Nightfall" puts every member of the Shannon family to the test after a meteorite explodes above Terra Nova, setting off an Electro Magnetic Pulse that renders all electronics useless. Well, every family member except for Josh who isn't given much of anything to do this week. Even Skye's friend Hunter, who we've barely gotten to know, is given more screen time than poor Josh.
