PBS: NO LONGER A REFUGE FROM CELEBRITY WORSHIP

— Normal was the old normal. The beauty of streaming old television shows on YouTube and elsewhere is that they offer a glance at a time before the present, when our popular culture was not entirely dominated by the veneration of wealth and celebrity.

This year, ABC’s summer onslaught of prime-time game shows almost all featured celebrities. As if we couldn’t bother to watch anyone else! The already notable are preventing everyone else from their 15 minutes of fame.

Even PBS has gotten into the act. As the new Fox series “Almost Family” reminds us, our “genetic material” is common to every member of humanity.

But the makers of the genealogical history series “Finding Your Roots With Henry Louis Gates Jr.” (8 p.m., PBS, TV-PG, check local listings) keep the accent on celebrity. Why trace the family history of just “anybody,” when you can find out the origins of Sarah Jessica Parker?

Tonight, the series really outdoes itself. We’re not just spending time with celebrities, but with bold-face names who are themselves the offspring of Hollywood stars!

Look for anecdotes about the ancestors of acting “royalty,” including Mia Farrow (daughter of director John Farrow and actress Maureen O’Sullivan); Angelica Huston (daughter of John Huston and granddaughter of Walter Huston) and Isabella Rossellini (daughter of actress Ingrid Bergman and director Roberto Rosellini).

I have nothing against any of these three individuals, who all may be interesting in their own right. But when we start obsessing about Hollywood “bloodlines,” we’re flirting with something creepy.

Keep reminding yourself: It doesn’t have to be this way. And until relatively recently, it wasn’t.

— What happens when lawlessness and contempt for due process flow from the very top? “Frontline” (10 p.m., PBS) presents the harrowing documentary “On the President’s Orders,” a look at the Philippines under President Rodrigo Duterte, a man who has encouraged the extrajudicial murders of thousands of citizens accused of taking or dealing drugs.

Filmmakers gained access to characters on both sides of this gruesome true story: a police officer trying to train his men to refrain from random killings and a loose gang of teens born into poverty who learn to navigate streets where criminal violence and police lawlessness can claim their lives at any moment.

“Orders” may be too gruesome for some. We follow one charismatic teen character from the streets to the autopsy table. It’s that kind of film. And it’s all true.
