1) Grand Cayman: Secrets in Paradise” debut, 10 p.m., Freeform. Reality shows like to be in pretty places, with pretty and/or wealthy people. This one is on a small (22 miles long) Caribbean island (shown here) that has busy bankers and 75,000 people. One is Elizabeth Chambers, a TV cook and personality; news arrives about the allegations toward her ex-husband, actor Armie Hammer.
2) “Shogun,” 10 p.m., FX. Two weeks from the finale, this lush miniseries reaches a turning point. Toranaga’s clan has been defeated and moves to Edo. Now John Blackthorne must choose – fight for the lord who turned his back on him or return to the original reason he sailed to Japan.
3) “Lopez vs. Lopez,” 8 and 8:30 p.m., NBC. Last week, this jettisoned its only strength. That was the fact Mayan had the upper hand — a good job and a home where her dad crashed.. Now she’s lost her job and works for him; tonight, he gives her husband makeover advice. At 10 p.m., NBC’s “Password” has Nikki and Brie Garcia, who wrestle as the Bella Twins.
4) “Finding Your Roots,” 8 p.m., PBS. After years of tracing the backgrounds of celebrities, Henry Louis Gates switched for this season-finale. He took requests from viewers and chose three; the result, tonight, is fairly interesting. It’s followed at 9 by the mid-section of a three-week Julius Caesar profile.
5) Movies. Meg Ryan mostly stepped aside from acting for nine years, before directing, co-writing and co-starring (with David Duchovny) in “What Happens Later.” Tom Cruise waited 36 years to make a sequel to “Top Gun.” The results? Her movie (9 p.m. today on Showtime) had an opening weekend of $1.6 miilion; his (8 p.m. on MGM+) was 126.7 million; overall, it has passed $1.5 billion.
