"Torchwood: Children of the Earth" (8 p.m., BBC America): Whatever you were planning to do this week, back out of it. Nothing is more important than watching this four-star miniseries, which airs five nights in a row. When the world's children all freeze at once and start chanting, "We are coming," Capt. Jack Harkness and his crew scramble to thwart the aliens. Jack is played by John Barrowman, who went to high school in Joliet and is seriously attractive. It's thrilling, funny and poignant. If you don't get BBC America, pretend to be friends with someone who does.

"The Wanted" (9 p.m., WMAQ-Channel 5): The premiere of the controversial show that follows a Green Beret, a Navy Seal and an investigative reporter as they hunt down war criminals.

"Dating in the Dark" (9 p.m., WLS-Channel 7): Is true love blind? Don't bet on it.
