1) “Blue Bloods.,” 10 p.m., CBS. Two key figures in CBS history link tonight. Ed Asner (shown here) arrived a half-century ago in “The Mary Tyler Moore Show”; Tom Selleck came 10 years later in “Magnum, P.I.” Combined, those shows spent five years in the Nielsen top-10, 11 years in the top-20. Selleck won an Emmy; Asner won seven, five of them in “MTM” and its “Lou Grant” spin-off. Now Asner, 90, plays the victim of a home invasion; Selleck, 75, plays his friend, the police commissioner.
2) “Hawaii Five-0,” 9 p.m., CBS. The network pulled a surprise recently, when it announced that “Five-0” will end its 10-season run on April 3. For now, here’s Jimmy Buffett’s seventh turn as pilot Frank Bama. A rancher is killed, after finding a skeleton on his land.
3) “Hillary,” any time, Hulu. The Hillary Clinton in this documentary is far more interesting than anyone we saw on the campaign trail. She fought (and won) long before that was fashionable. As a college freshman, she was president of Young Republicans; as a senior, she drew national attention by improvising a rebuttal of the Republican graduation speaker. An ardent feminist, she receded into her husband’s political career, then re-emerged. The story is richly told by the Clintons and many more.
4) “The Most Dangerous Animal of All,” 8 p.m. to midnight, FX. Studying his family roots, Gary Stewart began to suspect his father was the long-ago “Zodiac Killer.” This documentary traces his search. Like all FX or FXX originals, it goes to Hulu the next day. That means Hulu adds comedies today (the “Better Things” and “Cake” season-openers), then adds this show on Saturday.
5) And more: There’s serious drama on the streamers: Netflix has the “Spenser Confidential” movie, with Mark Wahlberg stepping into a detective role previously played by Robert Urich and Joe Mantegna; Amazon Prime has “ZeroZeroZero,” a series taking a global view of the cocaine trade. Want the exact opposite? Turner Classic Movies has “Beach Party” (1963) at 8 p.m. ET, “Muscle Beach Party” (1964) at 10 and, of course, “Beach Blanket Bingo” (1965) at midnight. They’re dim-witted, but fun.
