1) “Lucky Hank,” 9 p.m., AMC. Yes, there are way too many good shows (“Succession,” “Sanditon,” “Yellowjackets”) at 9 p.m. Sundays. But this one – rerunnning at 10:06 p.m. and 1:40 a.m. — is way too good to miss. Hank (Bob Odenkirk, shown here) clings to his faculty job at an obscure college, but his wife has interviewed for a job at a top school in New York. At a faculty dinner party, it all boils over in ways that are simultaneously funny and disturbing.
2) “Masterpiece: Sanditon,” 9 p.m., PBS. With only two episodes left, this elegant series leaps into crisis mode. Edward has run off with Colbourne’s niece, planning to marry her and get her fortune. Now the others try to intervene, before he can bed her – and, in the olde-England view – ruin her. That happens as all other relationships are in disarray. It’s a strong set-up for next week’s excellent finale.
3) “Succession,” 9 p.m., HBO, and more. Last week, this show – one of TV’s best – jolted viewers: Logan Roy, patrriarch and media mogul, died of a heart attack; now the power struggle shifts, with seven episodes remaining. HBO also has fresh shows to surround it. Tonight brings the season-openers of “100-Foot Wave” (8 p.m.) and of the final “Barry” season (10 and 10:30). Next week, “Somebody Somewhere” starts its second season.
4) “The Equalizer,” 8 p.m., CBS. This is a terrific series, but an elusive one. It took a three-month break, came back with six episodes, then was displaced on two Sundays by music – country one week, Beach Boys the next. Now it has the season’s final five episodes in a six-Sunday stretch. Tonight, an immigrant is accused of killing a congresswoman whom he was staying with. Robyn tries to clear him.
5) ALSO: “American Idol” (8-10 p.m., ABC) starts its annual trip to a Hawaiian resort; that concludes Monday, with viewers trimming the field to 20. And “Magnum P.I.” (9 p.m., NBC) has its second-to-last episode of the season, with a probe that puts Higgins inside a psychiatric hospital. They lead into ABC’s “The Company You Keep” and NBC’s “The Blacklist,” both at 10 p.m.
