Daily Best Bets

1) “What We Do in the Shadows,” 10 p.m., FX, rerunning at 10:34 and 11:08. The plot is familiar: An important visitor is coming; an odd family tries to seem normal. But this family has three vampires, a wise aide (shown here) and a lad who emerged from the chest cavity of a late colleague and keeps growing rapidly. Now a private-school official visits. “Shadows” ditches its usual droll style and offers a vampire version of a wild (and funny) drawing-room farce. Read more…

1) “Viva Las Vegas” (1964), 8 p.m. ET, Turner Classic Movies. A 24-hour Elvis Presley marathon starts at 6 a.m., It offers a couple zestful concert films – “Elvis on Tour” (1972), 2 p.m.; “Elvis: That’s the Way It Is” (1970), 10 p.m. — and lots of scripted ones. Some are awful, but “Viva” (shown here) has glitter, Ann-Margret and lots of vibrant music, led by the title song. There’s even a rare nod to Presley’s R&B roots, when he sings “What’d I Say?” Read more…

1) “City on a Hill” season-opener, 10 p.m., Showtime. Jackie Rohr is one of TV’s great characters, an FBI agent rippling with intelligence and rage. As last season ended (14 months ago), corruption probes grew and he turned in his badge. Now he’s near-bottom — to the delight of an honest prosecutor. Perfectly played by Kevin Bacon and Aldis Hodge (shown here), these two are great opposites. This opener also has strong moments for Corben Bernsen and Ernie Hudson. Read more…

1) “Saturday Night Live,” 11:29 p.m., NBC. We don’t expect big laughs from Benedict Cumberbatch. But his second hosting turn (with Arcade Fire as music guest) begins with a brilliant sketch (shown here): The draft of the decision overturning Roe v. Wade cited 13th-century English law. Here, he’s in 1235, pushing a law against abortion, sort of like the one banning pointy shoes. Exceptions for incest or rape? No way, someone says; “those are the only kinds of sex we have.” Read more…

1) “Secret Celebrity Renovation” season-opener, 8 p.m., CBS. Here’s the opener that was scheduled for last week, then nudged back. It offers two familiar star: Billy Gardell of “Bob (Hearts) Abishola” does a project for a friend’s mother(shown here). Rob Mariano (Boston Rob of “Survivor” fame) did a project for his parents last season; now he joins the show as a contractor. Read more…

1) “Top Gear,” 10 p.m., BBC America. The British have their own truck-driver shortage now, so the hosts switch gears. Accustomed to zippy little sports cars, they try behemoths. Paddy McGuinness (shown here), a truck-driver’s son, gets a 770- horsepower Scania, with high-tech details. He expects to visit greasy-spoon diners; instead, the truck-stop has sofas and a smiling barista. Despite trouble with accents and phrases, Americans will find this sort of fun Read more…

1) “The Green Planet,” 8 p.m., PBS. If you think you have trouble with a hot dry spell, consider the desert plants; some wait for a decade or longer for rain. Then they zoom into action; time-lapse film catches the stunning stretch when primroses and others briefly turn the desert colorful. This terrific hour with David Attenborough (shown here) shows how plants entwine, sharing their roots; and how cacti and others store water reserves. Read more…

1) “America’s Got Talent” and “Snake in the Grass,” 8 and 10 p.m., NBC. Next Monday, “Snake” (shown here) has its USA Network debut. First, it gets a bigger spotlight on NBC (USA’s corporate partner), behind “Talent,” the summer ratings-leader. “Snake” dumps four people (from “Survivor,” “Naked and Afraid,” etc.) in the wilds for 36 hours. They face challenges, while trying to figure out which one is secretly working against them. Bobby Bones hosts. Read more…

1) “The Great Giveback,” 9 p.m., HGTV. Melissa McCarthy seems to have lots of cousins, all of them taller than her. One is Jenny McCarthy, the actress and ex-Playmate; another is actress Jenna Perusich. Last year on “Celebrity IOU,” Melissa helped do a fix-up that Perusich designed for her dad (a retired Chicago cop) and mom. Now the two cousins (shown here) have their own show; tonight, they create a special room for a kindly pianist. Read more…

1) “Hotel Portofino” season-finale, 8 p.m., PBS. In 1920s Italy, Bella’s gorgeous little hotel caters to her fellow Englishfolk. Problems include a corrupt Fascist official and her scheming husband, who is learning about her far-away love. Now come key questions: Who stole the painting Cecil took from his family’s estate? Will his son Lucian choose the bland socialite or the sweet nanny (shown here)? What happens to Lucian’s closeted friend? There’s a lot here, some of it satisfying. Read more…
