1) “Grand Hotel,” 10:01 p.m., ABC. Deep in debt to crooks, Santiago had one solution: His step-daughter would marry a rich guy whose family would buy the hotel. Alas, she slept with a singer named El Rey; at the altar, the groom denounced her and attacked the singer. (Yes, it’s that kind of show.) Now Santiago’s biologic daughter (Denyse Tontz, shown here) wants to save the hotel with an El Rey concert; others have doubts. Also, Danny’s secret – he’s the brother of the missing worker – is discovered by another staffer.
2) “Legion” season-opener, 10 p.m., FX. Suddenly, we seem to be whisked into a 1960s LSD film. A teen (newcomer Lauren Tsai) is barraged by images telling her to do … something. She wades through a kaleidoscope of images and seems to be in her own personal wonderland. What’s going on? “Legion” fans have learned not to ask; David — who has been through many realities – finally returns, almost halfway through the hour. He’s played by Dan Stevens, far from the stiff reality of “Downton Abbey.”
3) “The Bachelorette,” 8-10:01 p.m., ABC. In Latvia, Hannah Brown and her nine guys range from bungee-jumping to market-going to one guy joining her for a ritual with sauna and spiritual elements. As ABC puts it: “The two connect with hot physical intensity.” It seems quite pleased about this.
4) “Years and Years” debut, 9 p.m., HBO. At 60, Emma Thompson is in a career renaissance. She’s subtly perfect in Mindy Kaling’s movie “Late Night” … she hosted “Saturday Night Live” … and now she plays a noisy businesswoman who pushes England toward chaos. All of that is seen through the eyes of a middle-of-the-road family, in a six-parter from Russell Davies, the brilliant writer of “A Very English Scandal,” “Torchwood” and many of the recent “Doctor Who” episodes.
5) “Islands of America,” any time, www.acorn.tv. Martin Clunes, star of the British “Doc Martin,” visits the colonies, with delightful results. The first hour finds opposite island worlds in Hawaii and Alaska. The second visits a lush (and, mostly, legal) marijuana business in Washington state and a paradise for seals in California, then goes to a Louisiana island that’s being swallowed by rising water. Two other hours range from Puerto Rico to Martha’s Vineyard.
