1) Shark overlap, cable. This is the day “Sharkfest” slides from the National Geographic Channel to Nat Geo Wild, where it will linger for two more weeks. But it’s also when Discovery starts “Shark Week” – an idea it created 32 years ago. At 8 p.m., Discovery returns to the site off the high-leaping “Air Jaws” (shown here). At 9, it claims to have an underwater confrontation between sharks and Mike Tyson. And at 10, it’s in New Zealand, where giant great whites, some 20 feet long, thrive.
2) “Celebrity Family Feud,” 8 p.m., ABC. Last Sunday, ABC rested its game shows so it could celebrate the start of the basketball season. Now basketball is confined to 3 p.m. ET (Spurs-Pelicans) and the games are back. This one is a rerun from last season: The first two teams are led by athletes (Terry Bradshaw and Adam Rippon), the second by teen actors (Skai Jackson and Hudson Yang).
3) “Masterpiece: Endeavour” season-opener, 9-11 p.m., PBS. It really is possible to try too hard, to have – as the “Amadeus” emperor put it – “too many notes.” As in previous years, “Endeavour” is beautifully filmed and subtly acted; unlike previous years, it throws a barrage of stories at us, never bothering to explain what they are. Only one mystery is solved (in an unsatisfying way); others will wait another two weeks. This is still worth trying, but you’ll need patience … and maybe a notebook.
4) “The Alienist” season-finale, 9 and 9:58 p.m., TNT. This all started with a search for the kidnapped baby of the Spanish consul; that continues, but now there’s a bigger and more lethal search. The result puts this show’s stiff, 1896 behavior and language alongside brutal torture, murder and more. Still, it does manage to solve the case, wrap up personal stories and leave room for a potential spin-off.
5) And more: “Surviving Jefferey Epstein” has the first half of its two-night, four-hour run; that’s 8 p.m. on Lifetime, rerunning at 10:03. It’s a documentary; there are also new, scripted hours, including: At 9 p.m., the “Perry Mason” season-finale on HBO; also, “Yellowstone” on Paramount and “The Chi” on Showtime;. At 10, “Wynonna Earp” on Syfy.
