1) “9-1-1” season-finale, 8 p.m., Fox. The series started with terrific work from Connie Britton as Maddie, a passionate 9-1-1 operator. She left – Britton had only planned to do one season – but returns two years later for this guest shot. Maddie (shown here) was one of the victims, when a train plunged off the tracks; people race to the rescue, including her ex-lover Buck. Then the second “9-1-1: Lone Star” episode reruns at 9:01.
2) “Asian Americans,” 8-10 p.m. PBS; concludes Tuesday. This compelling film starts with triumph: Chinese workers were key to building the 1,912-mile Transcontinentai Railroad. America celebrated in 1869 … then passed the Chinese Exclusion Act in 1882. One American native, visiting his parents’ homeland, needed an 1898 Supreme Court win to get back into the U.S. The second hour views the internment of 120,000 Japanese (the majority of them American citizens) during World War II.
3) “The Voice” semi-finals, 8-10 p.m., NBC. Last week, 17 people sang from home and viewers voted. Now nine remain — two on each team, plus Joanna Serenko (from Blake Shelton’s team), the wild-card winner. They perform and viewers vote; the results are Tuesday, setting up next week’s finale.
4) “Bob (Hearts) Abishola,” 8:30 p.m., CBS. This rerun has two stories, one so-so – the awkward relationship between Bob’s sister and Kofo, one of the workers – and one terrific: As Bob’s ex-wife (Nicole Sullivan) maneuvers back into his life, Abishola’s even demeanor is strained.
5) “Songland,” 10:01 p.m., NBC. Not long ago, Julia Michaels was the one pitching songs. As a teenager, she co-wrote songs for Selena Gomez, Demi Lovato and more, even co-writing the “Austin & Ally” theme song. But when she wrote “Issues,” she kept it for herself, getting 2018 Grammy nominations for the song and for best new artist. Now, at 26, she hears pitches from other songwriters.
