1) “Grey’s Anatomy” season-finale, 9 and 10 p.m. Thursday, ABC. One of the longest-running dramas in TV history wraps its 19th season. (Next year, it ties “Gunsmoke,” trailing only a pair of “Law & Order” shows.) The finale revolves around the wedding of Doctor Simone Griffith (shown here with her father) and Dr. Trey Delgado, in her grandmother’s backyard. That forces Meredith (Ellen Pompeo) to meet her ex-boyfriend Nick; it’s Pompeo’s first return since dropping out as a regular.
2) “NCIS: Los Angeles” series-finale, 9 p.m. Sunday, CBS. Here’s another long-running show, amid detoured wedding plans. Anna – a former Chicago cop and the estranged daughter of a former KGB agent – and Callen were planning their wedding, when chaos intervened. A federal agent is missing and some military-grade weapons have been stolen. “NCIS:LA” wraps a 14-season run, putting it among the top-10 scripted shows; a celebration follows at 10.
3) “American Idol” finale, 8-11 p.m., Sunday, ABC. Someone will become the 21st champion, joining a list that has Kelly Clarkson, Carrie Underwood, Scotty McCreery and lots of people who faded. That wraps a busy week for music shows: Tonight, “Idol” (9-11 p.m.) looks back at what’s happened so far; also, “The Voice” (8-10 p.m., NBC) has the top eight, eyeing next week’s finale. And Fox’s “Masked Singer” finale (8 pm, Wednesday) has Macaw and Medusa.
4) “9-1-1” and “9-1-1: Lone Star,” Fox. Both shows close their seasons, but with different futures. “Lone Star” (8-10 p.m. Tuesday) will be back on Fox next season; “9-1-1” won’t. It’s the network’s most-watched scripted show, but it’s also an expensive one — as demonstrated tonight: A series of car crashes leads to the collapse of an overpass, endangering civilians and rescuers. Fox didn’t renew it for next season and it will jump to ABC this fall.
5) “American Masters,” 9-11 p.m. Tuesday, PBS. When he reached the U.S. in 1964, Nam June Paik had lived in Korea, Japan and Germany. He was a classical pianist with no money and many ideas; in 1967, the topless cellist at his concert was arrested. Paik soon created a piece with a Buddha statue watching itself on TV; fame followed. He coined the phrase “electronic super highway” and mastered the electronics images that soon fueled music videos.
6) “True Lies” season-finale, 9 and 10 p.m. Wednesday, CBS. Fast and flashy, “Lies” has been a fun ride — but CBS won’t bring it back next season. Now it gets a big finish. Helen, a college professor, was startled to learn her husband Harry is a spy. She trained to join him, but that keeps jarring their home life. Now their daughter is dating the teen hacker who helped find the bad guys. Then a spy is missing; the case strains their relationship and reality.
7) “Young Sheldon” season-finale, 8 and 8:30 p.m. Thursday, CBS. It’s been a great year for this show, sparked by the relationship between Georgie, 18, and Mandy, 29. He’s a diligent dad to their baby, but he’s also the guy who lied about his age. She rejected his marriage proposal, but now she plans a spa weekend. Meanwhile Sheldon and his mom are heading to his summer classes in Germany … and a Texas tornado is nearing their home town.
8) “Law & Order: Special Victims Unit” and “Law & Order: Organized Crimes,” 9-11 p.m. Thursday, NBC. These shows linked last week when Benson and Stabler probed a dilemma – similar assaults, but with different DNA. Now the case has spread globally. In the first hour, Fin and Bruno help a victim who was assaulted a second time; Jet’s attempt to hack the dark web backfires. In the second, the U.S. attorney benches Benson and Stabler; Bell and Fin take over.
9) “Great Performances,” 9 p.m. Friday, PBS. We often expect King Richard III to be white and male, but that’s swept aside beautifully here. Danai Gurira, known for “The Walking Dead” and the “Black Panther” movies, brings power and subtlety to this Shakespearean role. It’s filled with rage and revenge … but that isn’t always the case on PBS. At 9 p.m. Sunday, “Masterpiece” wraps “Tom Jones,” with some closing twists that reflect its sunny, goofy nature.
10) More season-finales. Today, “All American,” 8 p.m., CW. Thursday, “Station 19,” 8 p.m., ABC; “Law & Order,” 8 p.m., NBC; “So Help Me Todd” and “CSI: Vegas,” 9 and 10 p.m., CBS. Friday, “SWAT,” “Fire Country” and “Blue Bloods,” 8-11 p.m., CBS. Sunday, “The Equalizer,” 8 p.m. CBS; “Simpsons,” “Great North” and “Bob’s Burgers,” 8-9:30, Fox. They’ll be back next season – including “SWAT,” which was canceled and then uncanceled.
