‘Law’ commences new season

Tonight’s might-see

“Law & Order” season-opener, 10 p.m., NBC. In the best “Law & Order” tradition, this hour will tug you on both sides.

Grown men were in a deadly fist fight. This was stupid, but was it a crime – and under which law?

There’s no easy answer. Before the hour ends, McCoy (Sam Waterston) has heard a fierce argument from Lupo (Jeremy Sisto) and several quiet ones from Cutter (Linus Roache).

Tonight’s might-see II

PBS’ “Medal of Honor,” 8 p.m. KSPS, 9 p.m. KUID. There are great stories here.

We meet Hershel Williams, the undersized corporal who kept crawling back for more flamethrowers. And Tibor Rubin, who survived both the Holocaust and an anti-Semitic Korean War sergeant.

There’s Drew Dix in the Tet offensive, rescuing civilians and capturing 20 prisoners. And Charles Liteky, a chaplain who carried 23 wounded men to safety, later returning his medal in protest. Despite so-so narration, this is a fascinating film.

Other choices include

“Dancing With the Stars,” 8 p.m., ABC. The results show, usually on Tuesdays, was delayed a day because of the election. “Pushing Daisies” rests for a week; “Private Practice” gets a stronger lead-in.

“Knight Rider,” 8 p.m., NBC. Mike and Sarah are stuck in a plane, trying to keep KITT from self-destructing.

“Legend of the Seeker,” 5-7 p.m., WGN America. If you missed the debut last weekend, here’s a second chance. Despite flaws, it’s the start of an epic fantasy that’s worth trying.

“Life,” 9 p.m., NBC. This show has had trouble getting noticed. Now it has a new Wednesday slot, nudging “Lipstick Jungle” to Fridays. Tonight’s hour strains credibility, offering a support group for mega-millionaires. Still, the main character (played by Damian Lewis) is interesting.

“Private Practice,” 9:02 p.m., ABC. As the clinic’s new leader, Addison takes a chance that puts the clinic in more danger.

“Dirty Sexy Money,” 10:02 p.m., ABC. During Letitia’s trial, Nick finds a dark secret about Nola Lyons, the prosecutor.
