TONIGHT'S MUST-SEE

"Friday Night Lights," 7 p.m., NBC. As the Panthers prepare for the semifinals of the state championship, a fresh question emerges: Where, exactly, will it be played? The answer leads to some unique football footage. It isn't terribly convincing, but it is riveting. Along the way, "Friday Night Lights" displays its unique rhythms, packing large impact into short sentences. Tonight's final line of dialogue is a perfect example.

"Jericho," 7 p.m., CBS. Even in the aftermath of nuclear blasts, things can get much worse. Tonight, life turns bleaker for the people of Jericho. Winter has settled in hard. Most of the electricity is out, heat is gone — and a new crisis hits someone who is key to the community. This hour beautifully portrays these tough Kansans during a time of crisis. It's intelligently written and solidly played. It also is overkill, one of three good dramas airing at 7 p.m. Wednesdays.

OF NOTE

"Bones," 7 p.m., Fox. A probe in a church cemetery brings a debate between the devout Booth and the skeptical Brennan. That propels a return visit to a therapist. He's played by Stephen Fry, who was Hugh Laurie's partner for some great comedy work in England.

"Journey to Planet Earth," 8 p.m., PBS. Nearly half the world's marine animals could become extinct during the next 25 years, this documentary says. The film is fairly flat and ponderous but partly makes up for that with passion and scope. It ranges from Florida and New England to China, Japan, Africa and Antarctica.

"Crossing Jordan," 8 p.m., NBC. Working a tough case involving a slain woman and a stolen baby, Jordan makes a key mistake.

"The Boomer Century," 9 p.m., PBS. The entire baby-boomer experience — past, present and future — is packed into this two-hour special. The history part merely restates the obvious with few esthetic touches. The second hour is much better, as we see changing views of adulthood. One man runs his prosperous business from (really) a tree house. Another, at 64, doesn't expect to retire soon from the family business. After all, his dad still works there at 101.

"Medium," 9 p.m., NBC. Miguel Sandoval, who plays Allison's boss, directed this episode, in which Allison dreams of a woman who appears to be possessed.

"Lost," 9 p.m., ABC. Hurley has fresh suspicions about Sawyer. Meanwhile, flashbacks tell us more about Nikki and Paulo.
