1) “The Masked Singer” opener, 8 p.m., Fox. Last season (shown here), this was a ratings hit – No. 12 in the overall Nielsen ratings and No. 3 – trailing only two football nights, among viewers 18-49. Now it’s the key to Fox’s makeshift fall schedule. It has all the usual oddities … plus, this time, a two-headed mask.
2) “America’s Got Talent” finale, 8-11 p.m., NBC. Fate has somehow decided that the summer ratings champ (“Talent”) should wrap up on the same night that a regular-season champ (“Masked Singer”) returns. Tuesday offered the last chance for this show’s top-10 to perform for viewers’ votes. Those performances will be rerun in tonight’s first hour; then – after much fuss – we’ll have a winner.
3) “I Can See Your Voice” debut, 9 p.m., Fox. Here’s a show designed to follow “Masked Singer”; it even has one of that show’s judges (Ken Jeong) as host. A contestant watches people lip-sync, then guesses which is a real singer. That person then does a music duet – for good or bad – with a star.
4) “Islands of Wonder,” 8 p.m., PBS. The mid-section of this gorgeous, three-week series visits Borneo. The third-largest island on Earth, it has room for 21 million people lots, of water and some mammals found almost nowhere else. The proboscis monkey has a nose that can be four inches or longer; the Bornean orangutan is the largest animal that can climb trees. Those and others are filmed beautifully.
5) “Looper” (2012), 7:58 p.m., Starz; and “Red” (2010), 8:05 p.m., Showtime. Some 35 years after he found stardom in “Moonlighting,” Bruce Willis can still be seen in terrific roles. “Red” shows up on cable a lot; it’s a clever tale that has Willis (now 65) learning that CIA killers aren’t allowed to quietly retire in suburbia. “Looper” shows up less often, but it has a brilliant time-travel plot, written and directed by Rian Johnson, who went on to triumph with “Knives Out.”
