WATCH THIS: SUNDAY
“Good Witch” (7 p.m., Hallmark): Cassie and Sam (Catherine Bell, James Denton) throw themselves into helping Middleton prepare for the town’s annual Fall Harvest in the feature-length romance “Tale of Two Hearts.” As the townspeople try to ensure they prevail over the competition from their rivals in nearby Blairsville, Grace and Nick (Bailee Madison, Rhys Matthew Bond) are sobered by the realization this is their last Halloween here. Trouble arises when the 100-carat ruby The Heart of Middleton is stolen from the museum.
“The Simpsons” (7 p.m., FOX): A hugely popular annual tradition for this long-running animated sitcom comes around yet again with the new “Treehouse of Horror XXIX.” In this 29th edition (in case anyone is struggling with Roman numerals), stories include an oyster-eating competition between Homer (voice of Dan Castellaneta) and Cthulhu, one of H.P. Lovecraft’s dark divinities.
“The Lover in the Attic: A True Story” (7 p.m., 10:03 p.m., 1:04 a.m., Lifetime): Actress Melora Walters (HBO’s ‘’Big Love”) makes her TV movie directorial debut with this 2018 melodrama, which reportedly is based on fact, yet plays like a film noir. Molly Burnett (“Queen of the South”) stars as Dolly Oesterreich, a 1930s-era American housewife whose boredom with her husband, successful businessman Fred (David Fierro), moves her to take a lover: repairman Otto Sanhuber (Kevin Fonteyne), whom she secretly moves into her attic.
“90 Day Fiancé” (7 p.m., 11 p.m., TLC): Six couples begin a frustrating process as they endeavor to bring their loved ones stateside and tie the knot within 90 days, lest they risk having their betrothed return to their home country, as this unscripted series opens Season 6. Among the new couples are Steven and Olga, both 20, of Bowie, Md., and Russia, respectively; Colt, 33, of Las Vegas and Larissa, 31, of Brazil; and Jonathan, 32, of Lumberton, N.C., and Fernanda, 19, of Mexico.
“Shark Tank” (8 p.m., ABC): Matt Higgins, co-founder of RSE Ventures and vice-chairman of the Miami Dolphins, joins Sharks Mark Cuban, Kevin O’Leary, Lori Greiner and Daymond John in the Tank for a new episode that features a mother-daughter team from Washington, D.C., who are seeking investors for their line of vegan soups. Siblings from Long Island, N.Y., pitch a product conceived by their father, who died before realizing his dream of appearing on this show.
“Halloween Wars” (8 p.m., 11 p.m., Food): In the new episode “Halloween Time Travel,” young actor Gaten Matarazzo (Dustin in “Stranger Things”) steps in as a guest judge for a challenge in which the final three teams — each comprising a pumpkin carver, a cake artist and a sugar wizard — are tasked with creating striking and delicious Halloween-themed displays that bend time and space. Hey, no pressure, right? Shinmin Li and Todd Tucker are the other judges; Jonathan Bennett is the host.
“Shameless” (8 p.m., 10 p.m., 12 a.m., Showtime): The rude comedy hits the midpoint of Season 9 in a fall finale somewhat pessimistically titled “Down Like the Titanic.” Facing pressure from Max Whitford (guest star Neal Bledsoe) over her investment recklessness, Fiona (Emmy Rossum) leans on kid sister Debbie (Emma Kenney) for support, while Tami (guest star Kate Miner) stumbles back into Lip’s (Jeremy Allen White) life.
