1) “America’s Got Talent” finale, 9-11 p.m. Tuesday and 8-11 p.m. Wednesday, NBC. The final 10 acts get one more shot. There are seven music acts (including an improv rapper and, shown here, a high school choir), plus dancers, acrobats and a spectacular projection act. Their performances Tuesday will be recapped at 8 Wednesday, setting up a two-hour finale.
2) “Murder in a Small Town” season-opener, 8 p.m. Tuesday, Fox. This was one of last season’s best surprises, with deeply human stories of a soft-spoken police chief, his librarian lover and diligent deputies. The second season starts with a domestic dispute gone bad. With the exception of an out-of-sync character (the mayor), it’s a terrific hour.
3) “Unforgotten,” 10 p.m. Sunday, PBS. A thickly layered six-parter ends powerfully; the victim was a thug, so the list of suspects is huge. That’s preceded by good finales for “”Professor T” and “The Marlow Murder Club,” at 8 and 9 … the same time that Fox starts the season for “The Simpsons,” “Universal Basic Guys,” “Krapopolis” and “Bob’s Burgers.”
4) “The Voice” and “Brilliant Minds” openers, 8 and 10 p.m., NBC. Getting a head start on CBS and ABC, NBC has a big week. The good news: “Voice” auditions begin, continuing from 8-9 p.m. Tuesday. The bad: “Brilliant Minds,” a smart show last season, tries too hard. A lurid flashforward shows this will be a tough year; an overbusy story follows.
5) “Alien: Earth” season-finale, 8 p.m. Tuesday, FX. This compelling show juggles opposite stories. One is fierce, with outer-space predators breaking free; the other is warmly human, with the minds of dying children inserted into synthetic bodies. The finale is mostly on the nasty side, but stick around:
In the final minutes, both stories merge brilliantly.
6) “The Lowdown” debut, 9 and 10:30 p.m. Tuesday, FX. Lee (Ethan Hawke) is a professional truth-teller, writing stories (for ragged little publications) about Tulsa corruption. This gives him little money and many beatings. Sharply written (by Sterlin Harjo of “Reservation Dogs”) and played, the first episode is a delight. The second gets a bit too chaotic.
7) “Law & Order Toronto: Criminal Intent” debut, 8 p.m. Wednesday, CW. Unlike other “L&O” shows, the original “Criminal Intent” spent extra time digging into the suspects’ minds and motivations. It ended in 2011, but now moves north, including a cop who’s the most all-knowing guy since Gilligan’s professor. The first two hours are sharp; the third is OK.
8) “Law & Order: Special Victims Unit” season-opener, 9 p.m. Thursday, NBC. The 27th season (the longest run ever for a drama) starts with the team trying to protect a key witness. That follows the 25th-season opener of “Law & Order,” with a probe pointing to an assistant district attorney. At 10, “Law & Order: Organized Crime” sees Stabler go undercover.
9) “Omara,” 10 p.m. Friday, PBS, following Hispanic Heritage Awards at 9. Omara Portuondo’s mother was ostracized for marrying a Black man. Her sister later moved to the U.S., but Omara, now 94, stated in Cuba, finding fame and Grammys. Laced with gorgeous vocals, this follows her on tour; it’s the third one, she says, that promoters call her “farewell tour.”
10) “Big Brother” finale, 8:30 p.m. Sunday, CBS, but 8 p.m. on the West Coast. This wraps a huge week for unscripted shows, with lots of openers. Wednesday has CBS’ “Survivor,” Fox’s “The Floor” and ABC’s “Golden Bachelor,” all 8 p.m., with ABC’s “Shark Tank” at 10. Thursday has Fox’s “Hell’s Kitchen” and “Special Forces”at 8 and 9 p.m., plus CBS’ “Amazing Race” at 9.
