1) “Undercover Boss” season-opener, 9 p.m., CBS. Waiting for its big shows to return, CBS has a loose blend – Sunday movies … a couple scripted shows from elsewhere … and lots of non-fiction. Now the amiable “Greatest #AtHome Videos” is followed by the 10th “Boss” season. Tonight has the CEO of TGI Fridays (shown here, right); coming are Bowlero, Club Med and Smoothie King, plus the mayor of Shreveport.
2) “Great Performances: Now Hear This” season-finale, 9 p.m., PBS. Mozart did it all – compose a piece, organize the orchestra and concert venue … then double as solo pianist AND conductor.; That notion impresses host Scott Yoo, a violinist and conductor who doesn’t mix the two. Now he coaches gifted pianist Stewart Goodyear to be soloist and conductor of Mozart’s demanding 20th piano concerto at Festival Mozaic. The result has gorgeous bursts of music, plus side trips near San Luis Obispo, Cal.
3) Double Dracula. You know this is October when you have your choice of Dracula films. Francis Coppola’s 1991 film is at 6 p.m. ET on BBC America; it’s beautifully crafted, with Gary Oldman, Winona Ryder, Keanu Reeves and, as Van Helsing, Anthony Hopkins. The 1931 version, with Bela Lugosi, is 8 p.m. ET on Turner Classic Movies. More horror follows on both networks … and on TNT (the 2017 “It,” 8 p.m.), USA (“Boo! A Madea Halloween,” 2016, 8:30) and all day on Freeform.
4) “Monsterland,” any time, Hulu. Yes, the streamers have other things in mind. (Netflix has just released Ryan Murphy’s reboot of “The Boys in the Band,” a half-century after the original made an impact with its gay characters; the cast is led by Jim Parsons, Zachary Quinto, Matt Bomer and Andrew Rannells.) But they’ll also join the October frightfest; this anthology has eight small-town horror tales.
5) And more: There really is some normal, Halloween-free TV, albeit via reruns. From 8-10 p.m., NBC has “American Ninja.” And at 10, “Blue Bloods” has an episode that aired six years ago, but feels current: Erin investigates a police officer accused of killing a suspect who was in custody.
