1) “Blue Bloods” finale rerun, 10 p.m., CBS. The final season ended with potential chaos for the police commissioner (Tom Selleck, shown here_ and his kin: New York’s gangs linking to demand amnesty for prisoners. That reruns today, a week before the debut of a well-crafted spin-off, “Boston Blue.” This finale also has key moments in the marriages of Erin and of her brother Jamie; also, Joe finally meets his cousin.
2) “Fire Country,” 8 and 9 p.m., CBS. The third season’s final episodes rerun, before the fourth begins next week. First, there’s a gas-station fire; then strong winds push a wildfire toward Edgewater.
3) “The Last Frontier” debut, Apple TV+. Frank (Jason Clarke) is a U.S. Marshal with a peaceful domain, in underpopulated Alaska. Then a plane crashes, freeing dozens of violent prisoners. Here are the first two (of 10) episodes, from the creator of “The Blacklist.”
4) More streaming. Amazon Prime has a profile of John Candy, the much-loved comedy actor who died in 1994, at 43; that arrives a day after its profile of football star Saquon Barkley. And Netflix has Keira Knightley in the mystery “The Woman in Cabin 10”; on Thursday, it debuted “Boots,” the true story of a closeted Marine in the 1990s.
5) MORE: At 6:45 p.m., IFC has “The Shining” (1980), a Stanley Kubrick classic that transcends the horror category. At 8, NBC has a new “On Brand With Jimmy Kimmel” and ABC reruns the “9-1-1: Nashville” opener. At 9, PBS has a portrait of King Records, the Cincinnati label that ranged from hillbilly music to James Brown. And at 8:08 ET, Fox has the Tigers-Mariners baseball-playoff game; the winner advances to the American League championship series.
