SUNDAY'S MUST-SEE

"The 50th Annual Grammy Awards," 7-10:30 p.m., CBS. Yes, the Grammys are important, mixing music's best. Album nominees are Kanye West, Amy Winehouse, Vince Gill, Herbie Hancock and Foo Fighters. Singles: Winehouse's "Rehab," Rihanna's "Umbrella," Foo's "The Pretender," Beyonce's "Irreplaceable," Justin Timberlake's "What Goes Around ... Comes Around." More impressive, each year, are the show's performances. Tomorrow night's show includes an epic gospel number, plus Rihanna linking with a reunion of The Time. An all-star youth orchestra backs the Foo Fighters. Also performing: Beyonce, Mary J. Blige, Feist, Alicia Keys, Brad Paisley, Carrie Underwood and more.

"Nature: Crash: A Tale of Two Species," 7 p.m., PBS. The horseshoe crab is an ugly creature that has been around for 350 million years. The red knot shorebird is an obscure one. These two are oddly linked, in a story that covers 10,000 miles. Director-narrator Allison Argo tells it beautifully.

OF NOTE

Pro Bowl, 11:30 p.m., Fox. With the real season over now, football's best players settle back for fun here in Hawai'i.

"Countdown to the Red Carpet: The 2008 GrammyAwards," 5 p.m., OCETV/KHON, digital 549. The writers aren't picketing, so there will be red-carpet glitz.

"Six Degrees Could Change the World," 8 p.m., National Geographic Channel. No more soft-sell; this documentary takes a scary look at global warning and the possible effects if the average temperature rose 6 degrees Celsius. The approach is tough and controversial, but the visuals are plush and beautiful.

"Masterpiece: Pride and Prejudice" opener, 8 p.m., PBS. This miniseries had its U.S. debut in 1995 on A&E; now PBS has its chance, as part of its "Complete Jane Austen" package. Jennifer Ehle and Colin Firth star in a three-week tale, intelligent and gracefully paced.

"The Wire," 8:30 p.m., HBO. Last week ended with a shoot-out that left Omar leaping from a top-floor apartment, then disappearing. Tonight, he begins a revenge vendetta. Meanwhile, McNulty continues his bizarre scheme, faking a serial killer.

"Breaking Bad," 8 p.m., 9 p.m. and 11 p.m., AMC. For Walt, the dying chemistry teacher who set up a drug lab, this is a crucial point: He must clean up the remains of one thug — and deal with another, who is still alive. Stick with this; it ends powerfully.
