1) “Prideland” and “The Lavender Scare,” 9 and 10 p.m., PBS (check local listings). Here’s a reverse time machine, showing us attitudes toward gays, present and past. First, Dyllon Burnside (“Pose”) journeys through his native South — he’s shown here in Texas — and finds a get-along mood. The early segments are bland, but then a church-school teacher in Mississippi passionately recalls her adjustment to learning her sons are gay. Contrast that with “Lavender,” a chilling account of an era when the federal government fired all gays.
2) “MacGyver,” 8 p.m., CBS. Mac and Desi try to help Syrian refugees who are pursued by human traffickers. And back home in Los Angeles, Bozer has his own problem: He’s trapped in a car that’s rigged to explode.
3) “Magnum P.I.” and “Blue Bloods,” 9 and 10 p.m., CBS. Both reruns eye subjects of current interest – accusations that someone is a bad cop, and the relationship between City Hall and the police force. First, Det. Katsumoto reluctantly asks Magnum and Higgins to help probe a cop suspected of stealing evidence. Then the mayor pushes the police commissioner to make staff changes he’s skeptical about.
4) “Da 5 Bloods,” any time, Netflix. Master filmmaker Spike Lee steps into new turf here – the Vietnam War and its lingering impact. Delroy Lindo, Clarke Peters and others play weary vets who return to ‘Nam, looking for their squad leader (Chadwick Boseman in flashbacks) and hidden gold. Also on Netflix is “The Woods,” a six-parter adapted from a Harlan Coben novel.
5) More movies. TV has temporarily become our movie theater; tonight (via video-on-demand) it has the much-anticipated premiere of “The King of Staten Island.” Judd Apatow directed and co-wrote, with Pete Davidson in an almost-autobiographical role. And on Amazon Prime is “Knives Out,” with its Oscar-nominated screenplay creating a wonderful blend of comedy, drama and murder mystery.
