Mike Hughes on TV

1) “Krapopolis” debut (shown here), after football (about 8 p.m. ET), Fox. Tyrannis has this theory that people can live peacefully in cities. That’s viewed skeptically by his mom (a self-obsessed shapeshifter), dad (half-human) and sister (really macho). In tonight’s second episode, Olympic-type games implode. This is a broad comedy from the “Community” and “Rick and Morty” producer. It’s inconsistent, but a fun piece of the cartoon line-up that starts next Sunday. Read more…

1) Football, 7:30 p.m. ET, NBC. Two top-10 teams collide, with Notre Dame (shown here) hosting Ohio State. That’s on the second Saturday this year (and the second one ever) when five broadcast networks have primetime games. Also at 7:30 p.m.. ABC has Texas at Baylor and CBS has Iowa at Penn State. CW has Georgia Tech at Wake Forest at 6:30 p.m.; Fox has Oregon State at Washington State at 7, then Southern Cal at Arizona State at 10:30. Read more…

1) “IHeartRadio Music Festival,” 10 p.m. ET (7 p.m. PT), Hulu; continues Saturday. This used to give the CW network a vibrant start to its fall season. Now, instead, it’s livestreamed. Ryan Seacrest hosts from Las Vegas, with a line-up that has country (Tim McGraw, Kane Brown), rap and hip hop (Public Enemy, Lil Wayne) and waves of pop and R&B – Kelly Clarkson, Lenny Kravitz (shown here in a previous show), Sheryl Crow, Miguel, TLC, Fall Out Boy, Foo Fighters and more.

1) “American Ninja Warrior,” 9-11 p.m., NBC. In two weeks, NBC will fill this spot with new episodes of “Transplant” (a fairly good Canadian drama) and reruns of “Dateline.” For now, it reruns the “Ninja” special (shown here) from Monday – a relay race involving people who are couples in real life. That’s preceded at 8 p.m. by a “Password” rerun that has Jimmy Fallon and Meghan Trainor. Read more…

1) “MasterChef” finale, 8-10 p.m., Fox. The South team has dominated all season. Last week, it had three people in the final six … but then two were ousted. That leaves Jennifer Maune (shown here), 42, a mother of six and lifestyle blogger who’s been a cheerleader, Junior Leaguer. real-estate salesperson and more. She faces people from the Midwest (Grant Gillan, 32, a brewery sales director) and West (Kennedy U., 26, a festival vendor). Each prepares a three-course dinner. Read more…

1) “America’s Got Talent,” 8-10 p.m., NBC. It’s time to fill the last spots in next week’s finals. Tonight’s contestants come from Russian Japan, Brazil, South Korea and Tanzania. They range from a 7-year-old dancer to a 61-year-old magician. There’s another magician, a dance group, an acrobat duo and a hula hoop aerialist, plus three solo singers, a duo (Trailer Flowers, shown here) and a chorus. Viewers will vote; on Wednesday, at least two acts will learn they’re in the finals. Read more…
