1) “NCIS” season-finale, 9 p.m. today, CBS. The 21st season ends, for a show that seems eternal. “NCIS” has already spawned four spin-offs and more than 1,000 episodes. It will be back next sason, alongside a prequel. Tonight, Parker and Knight (Gary Cole and Katrina Law, shown here, left and center) are trapped in a ship that’s about to be sunk.
2) “Next Level Chef” finale, 8 p.m., Fox. This started with an even split — five professional chefs, five who just did social media and five who cooked at home. The pros faded quickly; only one reached the final seven. That’s Zach Laidlaw, 34, who is now in the final three. He faces Christina Miros, 35, a home chef, and Gabi Chappel, 29, a social media chef. One of them will win $250,000 and a mentorship.
3) “The Voice” (today and Tuesday, NBC) and “American Idol” (Sunday, ABC), 8 p.m. “Voice” expands to two nights a week, after “Idol” trimmed to one. Today, 12 “Voice” singers have their first live telecast, with viewers voting afterward; on Tuesday, eight (plus one instant save) will go to the semi-finals. On Sunday, five “Idol” singers will do Disney songs; three will go to the May 19 finale.
4) “Bob (Hearts) Abishola” series finale, 8:30 p.m. today, CBS. A great – and, perhaps, underappreciated — show ends its five-year run. It began with a meeting of opposites – a casual Midwesterner and an intense Nigerian immigrant. Each brought a quiet decency, plus a batch of eccentric relatives. He sold the family business; she’s a nurse, pondering medical school. Good people reach new crossroads.
5) “Reginald the Vampire” season-opener, 10 p.m. Wednesday, Syfy. After the brutal “Chucky,” Syfy redeems itself with this genial show. Reg (Jacob Batalon) is a slushy clerk who became a vampire. The good news: His friend (Mandela Van Peebles, son of Mario) could be the local vampire king. The bad: Being a vampire, Reginald and his co-workers have found, “is a relationship obstacle.”
6) “The Farmer Wants a Wife” finale, 9 p.m. Thursday, Fox. The four guys are each down to two choices. Ty, 41, is the oldest; he’s with Megan (a teacher) and Melody (a nurse), each 31. The other guys are in their 20s. One prospect (Sydney, 22) is a construction worker. Others have jobs – digital marketing, communications associate, social media coordinator – you might not expect on the farm.
7) “Elsbeth,” 10 p.m. Thursday, CBS. Each week, this show creates a delightful guest role for a killer or victim or both. This time Elizabeth Lail (the beauty from “You” and “Ordinary Joe”) has turned an injury into a mega-business. It’s a bright challenge for the ever-eager Elsbeth, on a night that starts with two episodes of “Young Sheldon,” which ends its seventh and final season a week later.
8) “Hamlet,” 9 p.m. Friday, PBS. The annual Broadway spree will span four Fridays, stuffed with talent. Two plays – this one and the Tony-nominated “Purlie Victorious” – are directed by Kenny Leon; two concerts include Audra McDonald. Each is impressive, but the plays – gushing with turbo-paced dialog – aren’t for everyone. Brilliantly acted (in Central Park), “Hamlet” remains a challenge.
9) “ABBA: Against the Odds,” 8-10 p.m. Saturday, CW. Fifty years ago, ABBA’s “Waterloo” became the first Swedish winner of the Eurovision Song Contest. The group, which had only been singing in English for a year, soared. It had nine No. 1 singles in England (but only one, “Dancing Queen,” in the U.S.), plus a Broadway musical, two movies and now roughly the 12th documentary.
10) “Interview With the Vampire” season-opener, 9 p.m. Sunday, AMC. Claudia – the young vampire (5 in the book, 11 in the movie, 14 here) with an adult soul – has been recast. She’s played by the richly emotive Delainey Hayles. As the season starts. She and Louis are in post-war Romania. There are fierce and gory moments, before they can return to the beauty of 1940s New Orleans.
