1) “So You Think You Can Dance” finale, 9 p.m., Fox. Two gifted dancers (shown here with host Cat Deely), trained in opposite styles, remain. Keaton Kerrmode, 20, is a husky guy who was a 190-pound running back and safety in small-town Indiana; he’s a contemporary dancer. Alexis Warr, 21, trained in the Utah dance studio where Derek Hough began, then backed him on tour. She hopes to be the show’s first ballroom champ.
2) “Resident Alien” return, 10 p.m., Syfy. One of TV’s best shows – juggling droll humor and sci-fi adventure — is back from a five-month break. “Harry” (an alien who killed Harry and uses his body) – was about to be killed. Instead, Asta (one of the few people who knows his secret) shot the gunman. She’s in shock, while Harry – who lacks social skills – and D’Arcy plan a cover-up. There’s more, including a nasty alien baby and an intense alien-hunter.
3) “Abbott Elementary,” 9 p.m., ABC. Now this show really has our attention. It had already drawn seven Emmy nominations, including best comedy. Now it has swept the Television Critics Association awards, winning for program of the year and best new show, plus ones for Quinta Brunson as writer and star. Here, we see Janine (Brunson) delighted – briefly – when her college best friend gets a job teaching at the school.
4) “Password,” 9 p.m., NBC. Competing against Jimmy Fallon is Heidi Klum, who foresees a problem: This is a word game and her first language was German, not English. Still, she makes it fun, in an hour that is (like Tuesday’s opener) entertaining, despite being too hyper.
5) “Reservation Dogs,” any time, Hulu. Bear’s life is adrift. He’s 17, out of school, going nowhere. He’d planned to flee to California with Elora and friends, but she dumped him. Now he tries an abrupt detour – his first real job, in a field (roofing) he knows nothing about. The result is pensive and subtly moving; then the final minute sets up next week’s superb episode.
