1) “The Blacklist” season-finale, 10 p.m., NBC. After eight years of tangled twists and smart dialog, “Blacklist” might be ready to share a few secrets. Elizabeth Keen (Megan Boone) has shattered her FBI career, while obsessing on catching Raymond Reddington (James Spader), the former mentor who killed her mother. (They’re shown here.) Now he has a disturbing request, before he’ll reveal his true identity.
2) “In the Dark” season-opener, 9 p.m., CW. At its core, this is a nicely layered drama about Murphy, who is young, blind and cynical. On top of that, however, is a plot that keeps plunging her deeper into crime schemes. Now Nia, the drug boss, is dead; Josh, the IRS agent, knows that Murph and her friends are involved. Also, the police start to confront their corruption.
3) “MasterChef,” 8 p.m., Fox. Last week, the show wrapped up its auditions and emerged with 15 home chefs, from a 22-year-old student to a 59-year-old hospice nursing assistant. It’s an interesting group, including a construction worker, a bartender, a lifestyle coach, a radio host, an animal trainer and an environmental engineer. Now, with Chef Morimoto as guest judge, the competition begins.
4) “Show Boat” (1951), 8 p.m. ET, Turner Classic Movies. This is the third film version of a musical filled with great songs – “Bill,” “Can’t Help Lovin’ That Man” and, especially, “Old Man River.” It’s highly regarded, but softened the once-controversial story of a light-skinned African-American who passed for white. Resisting casting Lena Horne, a light-skinned African-American, it chose Ava Gardner.
5) “The Bold Type,” 10 p.m., Freeform. In this final season, the friends’ lives have become less tethered and more … well, free-form. Kat struggles to launch her campaign to give ex-felons a second chance … Sutton, who is divorcing, gets a call that could shatter the progress she’s made in therapy … And Jane, given new responsibilities at the magazine, faces her biggest challenge.
