What’s Worth Watching: ‘The Big Bang Theory’, ‘Superstore’, ‘Mom’, ‘Legends of Tomorrow’ and more for Thursday, November 3

The Big Bang Theory (8/7c, CBS): 10 seasons in, this hit sitcom has found renewed comic energy by putting that oddest of couples Sheldon (Jim Parsons) and lovelorn Amy (Mayim Bialik) in close quarters as temporary roommates—taking over Penny’s (Kaley Cuoco) apartment to the delight of newlyweds Penny and Leonard (Johnny Galecki), who get to enjoy a little alone time. Little wonder that Amy also wants to keep the cohabitation charade going, which is why she lies about the progress of her own home’s repairs. Which is also why the latest edition of “Fun With Flags” is being filmed in Penny’s pad.

Superstore (8/7c, NBC): Everyone’s getting political this time of year, and in a storyline reminiscent of this week’s Fresh Off the Boat, Cloud 9 becomes a polling place as political dissent breaks out among the staff, and Mateo (Nico Santos) is desperate to hide the fact that he’s undocumented.

Mom (9/8c, CBS): Rosie O’Donnell returns as Bonnie’s (Allison Janney) ex, Jeanine, who tempts Christy (Anna Faris) with a job offer that could derail her law-school ambitions. Her presence also stokes Adam’s (William Fichtner) understandable curiosity about Bonnie’s flexible sexual history.

Inside Thursday TV: In the latest twist in time-travel adventures, The CW’s DC’s Legends of Tomorrow (8/7c) finds the team in 1863 in an altered Civil War where the Confederate Army has been overrun by zombies. And you thought The Walking Dead’s Negan was a rebel. … NBC’s The Good Place (8:30/7:30c) has been invaded by residents of “the bad place,” including a mischief-maker played by Parks and Recreation’s Adam Scott. All of which is making the afterlife a living hell for Michael (Ted Danson). … Joe Walsh appears in an episode of FX’s Better Things (10/9c) in which Sam takes Max (Mikey Madison) to a concert and becomes a cool mom—for a fleeting moment.
