* MIKE & MOLLY. 8:30 p.m., CBS3.
Back a little early thanks to a cancellation (RIP "The Millers"), the show begins its fifth season with Molly (Melissa McCarthy) returning from an eight-week stint at the University of Iowa's writers workshop having sold a book. Mike (Billy Gardell), who held down the fort at home while Molly was away, has some adjusting to do.
* REGARDING SUSAN SONTAG. 9 tonight, HBO.
Patricia Clarkson gives voice to the late Sontag's writing in this frank and often gossipy look at the provocative critic, novelist and filmmaker whose advice to 2003 graduates of Vassar was, "Don't take s---. Tell the bastards off."
* SONS OF ANARCHY. 10 p.m. Tuesday, FX.
"Sons," an hourlong drama that seldom ends on the hour - and that has kept me up many a night - will take its last wild ride in a series finale that's reportedly expected to run 1 hour, 45 minutes. After which fans might not be able to sleep much, anyway.
* DINOSAUR 13. 9 p.m. Thursday, CNN.
Sundance Festival entry about the fight over "Sue," the Tyrannosaurus rex skeleton found in South Dakota's Black Hills in 1990, shows just how complicated science can get when property rights become an issue.
* MARCO POLO. Netflix, Friday.
In the streaming service's lush new costume drama, Lorenzo Richelmy stars as the young Venetian merchant and explorer who's left behind by his father in the court of Kublai Khan (Benedict Wong). All 10 episodes will be released at once, though I don't see myself bingeing on this one in a single weekend.
