1) “Lovecraft Country” debut, 9 p.m., HBO. Some of science-fiction’s favorite names are linked here. J.J. Abrams (“Lost”) and Jordan Peele (the “Twilight Zone” reboot) are among the producers. Like Peele’s “Get Out,” this blends racism with other horror. On a road trip to find his father and his legacy, a black man confronts racists and the sort of monsters envisioned by long-ago author H.P. Lovecraft. Jonathan Majors and Jurnee Smollett-Bell (shown in this poster) star with Courtney Vance.
2) Penultimate episodes. Three dramas set up next week’s season-finales. On “Yellowstone” (9 p.m., Paramount), the past looms for Jamie (the lawyer son of ranch-baron John Dutton) and Rip (a ranch hand); next week, John battles developer Roarke Morris for control of the land. On “Endeavour” (9 p.m., PBS), there’s a new story set in a Pakistani restaurant; previous cases will be resolved next week. On “NOS4A2” (10 p.m., AMC), Vic prepares for next week’s final collision with Charlie Manx.
3) “Supernatural,” 9 p.m., CW. The brothers need Rowena’s help keeping the evil souls away. That’s no surprise – there are lots of evil souls in this show – but here’s the bigger surprise: This rerun has been inserted instead of “Taskmaster,” which was instantly canceled. In England, “Taskmaster” (a droll sort of game show) is a hit – 10 seasons, 85 episodes, a British award for best comedy. In the U.S., it aired once, then was replaced last Sunday by “Supernatural,” tying the record for quickest cancellation.
4) “Democracy 2020: Convention Kickoff,” 10 p.m., Fox News Channel. We’re getting to the big stuff now – the Democratic convention this week and Republican next. Both will be Monday through Thursday, with the key moments at 10. Big networks will pay some attention, but the cable channels and PBS will be intense. Fox News offers a preview, hosted by Bret Baier and Martha MacCallum.
5) “To Catch a Thief” (1955), 8 p.m. ET,Turner Classic Movies. Alfred Hitchcock’s fun and elegant romp has Cary Grant (as a master thief), Grace Kelly and the French Riviera. If you really prefer “Star Wars” characters? TNT has “Star Wars: The Force Awakens” (2015) at 2 and 11 p.m., sandwiching “Rogue One” (2016) at 5 p.m. and “Solo: (2018) at 8.
