Juniors in jail
Michael Kenneth Williams, best known as Omar in "The Wire," is more than just the narrator in the season premiere of "Vice," sharing the sins of his past as he navigates the current state of juvenile justice in America. While the episode chastises the legal system, it also takes time to feature programs offering solutions and brave youngsters doing their best to avoid their parents' criminal paths. At one point, Williams almost bursts into tears; you might, too.

Out of the woodshed
After a 10-year absence, "Trading Spaces" returns with almost all the original crew in tow. In the two-hour season premiere, you're quickly reminded why the show was so addictive, with the now-famous designers plastering their wacky concepts — and egos — all over the participants' walls.

High and mighty
"Aerial Cities," which looks at America's urban areas from the viewpoint of a soaring Superman, starts off by flying over a Las Vegas that blurry-eyed casino players rarely appreciate. It's a fairly impersonal presentation — unless you like your characters looking like ants — but the camera work is stunning.

Lady Eve
Sandra Oh, sorely missed on "Grey's Anatomy," scrubs in as a MI5 security officer hot on the trail of an eccentric assassin in the new series "Killing Eve," created by "Fleabag's" Phoebe Waller-Bridge. Oh brings the same blend of determination and exasperation that made her Christina Yang the heart and soul of "Grey's," and Waller-Bridge's killer dialogue serve both her and her opponent, Jodie Comer, well.
