1) “Debris” debut, 10 p.m., NBC. When an alien spacecraft exploded, it scattered debris over the hemisphere. Those chunks have an other-worldly power to manipulate physics (including a floating body, shown here) and feelings. Now officials, working in secret, try to find and suppress the debris; bad guys want to harness the energy. “Debris” faces an eternal problem: Networks often cancel sci-fi shows abruptly, leaving crises in limbo. Still, this one can tell a self-contained story with each piece found; the opener packs strong emotions.
2) “The Voice” opener, 8-10 p.m., NBC. This is the 20th edition and Blake Shelton has been around for the whole ride. He’s already had seven winners and, for a time, was considered the “Voice” master. Then Kelly Clarkson arrived; she’s had three winners in six seasons. They’re joined this time by John Legend (one winjer in four seasons) and Nick Jonas (zero in one).
3) “Snowpiercer,” 9 p.m., TNT, rerunning at 10. This gripping hour oozes with desperation. Melanie (Jennifer Connelly) is the genius who designed Wilford’s train, the only place humans can survive the planet’s fierce cold. Now she’s left it, to find a research station. This is basically a one-person episode, albeit with brief flashbacks and some conversations she imagines. It’s beautifully filmed and acted, but not a fun way to spend a winter evening.
4) “Bob (Hearts) Abishola,” 8:30 p.m., CBS. Here’s a rerun of the season-opener. It’s a good one that has Bob buying an engagement ring for Abishola, with her uncle being semi-helpful. There are complications, of course, including the potential complications of a traditional marriage.
5) “9-1-1: Lone Star,” 9 p.m., Fox. Owen (Rob Lowe) feels out-of-place, when his girlfriend (Lisa Edelstein) moves in. Also, Tommy frets when her husband seems like their children’s primary parent. Then there are the 9-1-1 calls, including an extra body at a funeral.
