1) “Masterpiece: Poldark” season-opener, 9 p.m., PBS. The final season begins, for an epic that has a cinematic look and giant plot twists. This busy (but well-crafted) opener includes arson and an assassin, plus love, hate and political corruption. Part is in London, where Ross (a member of Parliament) rushes to help a friend, as the slavery issue rages. And part is back home (shown here), amid the beauty of Cornwall. Ross’ wife faces threats, his first love Elizabeth is dead and Elizabeth’s widower seems to be losing his sanity.
2) “The Simpsons” season-opener, 8 p.m., Fox. In an era of “privatized” prisons, this was inevitable: The school sends Lisa – the good kid – to privatized detention. Meanwhile, Homer is lured by the notion of “monetized” videos. It’s a funny look at our greed-ized world. It also makes up for the fact that “Bless the Harts” follows with a low-wit, no-fun debut at 8:30.
3) “The Durrells in Corfu” season-opener, 8 p.m., PBS. Louisa (the superb Keeley Hawes) moved to this Greek island out of cost-cutting desperation. There, she could support (barely) her four children, on her British widow’s allowance. Now one son is a semi-successful author, his siblings are floundering and Louisa is ready to take in lodgers. She’s been downcast since splitting with Spiros, who’s married. In its smart way, this 1930s drama makes despair seem entertaining.
4) “God Friended Me” season-opener,” 8:30 p.m. in many places, but 8 p.m. in the West, CBS. It turns out that another person is getting friend suggestions from the “God account.” That’s Joy (Jessica Lu), introduced briefly in the season-finale. Miles works with her, while Cara is in Paris, working on a book.
5) “The Rookie” season-opener, 10 p.m., ABC. Nolan (Nathan Fillion) is still a police rookie, now six months into his training. He and his colleagues feel the impact of an attack, with Bradford’s life in danger. The good news: Nolan’s romance with Jessica (Sarah Shahi) is progressing.
