1) “The Conners” series finale, 8 and 8:30 p.m., ABC. An oft-terrific series (shown here) concludes after 16 seasons, spread over 37 years. It started as “Roseanne,” dropped Roseanne Barr (and killed her character) and persisted. The finale brings key relationships, a lawsuit and some fond farewells.
2) “Changing Planet” season-opener, 10 p.m., PBS. Here are two projects – one urban, one rural – rescuing ailing rivers. In Paris, we see the rush to clean the Seine in time for swimming at the 2024 Olympics. And in Oregon, the 259-mile Klamath was suffering. Members of the Yurok Tribe fought to have the dams removed and salmon-fishing revived.
3) “Wild Cards,” 8 p.m., CW. A week before the season-finale, Ellis closes in on the person responsible for his brother’s death. The probe takes him to a jazz club, where Max goes undercover as a singer
4) “Sherlock & Daughter,” 9 p.m., CW. Last week saw a young American travel to London, convinced that Sherlock Holmes is her father. He disagreed, but now they’re working together, probing the kidnapping of her friend, the ambassador’s daughter. In a good episode tonight, she figures out what really happened, then faces fresh complications.
5) “The Floor” finale, 9:02 p.m., Fox. Nine people remain, competing over such categories as “trees,” “weddings,” “boy bands” and “Fortune 500.” Now one will win $250,000. That follows “The Masked Singer,” with the final five going for a spot in next week’s semi-finals.
