1) “CBS Evening News,” 6:30 p.m., CBS. This is the day Norah O’Donnell (shown here) takes over multi-duties; she’s anchor and managing editor of the newscast … anchor of political events … and occasional “60 Minutes” correspondent. That puts her on Murrow/Cronkite/Rather/Couric turf and she starts with a subject Walter Cronkite savored, the moon launch. Tonight, she discusses the future with space entrepreneur Jeff Bezos and with Caroline Kennedy, whose father propelled the moon program.
2) “Sharkfest,” National Geographic. Imagine watching 200 sharks devour a whale carcass. Or seeing 700 reef sharks on a feeding frenzy. In “Great Shark Chow Down,”scientists and cinematographers relive five mass events. That’s at 10 p.m. and 1 a.m., setting a pattern for this week – shark reruns at 3 p.m. … new “When Sharks Attack” hours at 8 and 9 … a special at 10 … and the whole thing rerunning from 11 p.m. to 2 a.m. Then come reruns Saturday, before this moves to Nat Geo Wild on Sunday.
3) “The Bachelorette,” 8-10:01 p.m., ABC. Last week’s hometown visits didn’t help much. Hannah Brown quickly gave roses to Peter Weber (a pilot) and Tyler Cameron (a contractor), but couldn’t decide between Luke Parker (an import/export manager) and Jed Wyatt (a singer/songwriter). She ended up dumping no one, leaving a final four for the second straight week.
4) “Molly of Denali” debut, 8:30-9:30 a.m., PBS; also, noon, 7 p.m. and 3 a.m., PBS Kids. This new animated series has a snappy title and a fresh setting, at the edge of America. In Alaska, Molly savors the outdoors and a loving family. But there are also some serious glances at her native roots and the biases her family has faced. It’s a solid start to a promising series.
5) “London Kills.” any time, www.acorn.tv. On one hand, each of the five episodes has a self-contained crime story. The season-opener – some remains found buried at a student house – is terrific … although not quite as great as the hyperactive background music thinks it is. And alongside that is an ongoing mystery surrounding one of the cops (Hugo Speer): His wife is missing; gradually, his colleague (Sharon Small) has doubts about him, adding an extra layer to a strong story.
