1) “48 Hours” season-opener, 9 and 10 p.m., CBS. It’s the 36th season for the show, with most of that time spent on true-crime tales. Erin Moriarty, for instance, has been covering the Gilgo Beach murders since 2010. This is the show’s sixth report on the case, now adding an interview with a co-worker of Rex Heuermann, the arrested suspect who’s shown here. The second hour probes the murders of four Idaho State students.
2) “Saturday Night Live,” 11:29 p.m. (or later, with a football overrun), NBC. Ana de Armas has been busy in the last four years. She co-starred in a great film (“Knives Out”) and a very good one (“No Time to Die”); she got an Oscar nomination in awful one (“Blonde”). She did five more movies and hosted this “SNL,” with Karol G as the music guest.
3) “Great Chocolate Showdown,” 8 p.m., CW. This began as a Canadian show, but now the CW is co-producing it … which sort of explains why this season’s 10 contestants included seven Americans. Now that’s down to the final five. In the first challenge, they bake chocolate bread and make a deli dessert sandwich. In the second, they make a dessert that matches a movie genre.
4) “Shakespeare and Hathaway,” 7 and 8 p.m. ET, Ovation. This show is set in Stratford-Upon-Avon … where, we’re told, the only statue of a woman is of a fictional one (Lady Macbeth) created by a man. Feminists protest a new museum … but are they involved with the murder that follows? As usual, there are schemes, secrets fun characters and convenient solutions. The second hour involves (really) the world of competitive hairstyling.
5) College football. Last Saturday brought a first – a primetime game on all five of the major broadcast commercial networks. Tonight settles for three of those, with games at 7:30 p.m. ET on ABC (Pittsburgh-West Virginia) and NBC (Syracuse-Purdue) and 8 p.m. on Fox (Texas Christian-Houston). There’s more all day … and at night on ESPN, ESPN2, Fox Sports1 and the CBS Sports Network.
