1) “The 100” season-opener, 9 p.m., CW. A nice nap is helpful, but this goes too far: Clarke (Eliza Taylor, shown here) and friends were in a sleep state for 125 years. Now they’re awake (and, one assumes, refreshed), with a task: Colleagues feel they’ve found a planet that can support life. “The 100” began with 100 people trying Earth; this hour, a good one, has a landing party of eight, including Clarke, Bellamy and the relentlessly annoying Murphy. In the ship are Clarke’s mom and the relentlessly annoyed Octavia and Raven.
2) “1969,” 10 p.m., ABC. This six-week series will get to the moon-landing, but tonight it has the Manson murders. ABC interviewed two women who weren’t involved with those, but were among Charles Manson’s followers. Both met him as teens: Dianne Lake was 14; she testified against him three years later, then hid her past for generations. Lynette “Squeaky” Fromme was 19 when she met Manson; she was arrested after a 1975 attempt to shoot Gerald Ford and spent 34 years in prison.
3) “Fosse/Verdon,” 10 p.m., FX. We’ve seen Bob Fosse be miserable after failure; now we see he was no better in triumph. His “Sweet Charity” (1969) flopped with critics and at the box office, but 1972-73 brought the “Cabaret” movie, “Pippin” on Broadway and “Liza With a Z” on TV; Fosse crumbled. It’s a great hour, beautifully directed by Jessica Yu, with a Fosse-quality hallucination scene.
4) “The Bold Type,” 8 p.m., Freeform. Last week’s episode saw two friends consider major detours – Kat as a candidate for alderman, Sutton as a fashion designer. Tonight’s fairly good episode sees both face quick obstacles … while their boss sees a growing threat to her job.
5) “Frontline,” 10 p.m., PBS (check local listings). Two days before Holocaust Remembrance Day, here is a quietly affecting documentary. “The Last Survivors” visits people – children then, now at or near 90 – who were in death camps. “I have not been able to cry,” one says, “because I think crying would have no end.” Another recalls: “I would look at the flames and think, ‘Which is my mother?’
