Three things to watch this week

Tonight: “Canterbury's Law” sounds like the name of a '70s show, but from the opening scene it's clear this legal drama is free of the latent sexism that marked the decade of “Police Woman” and “Get Christie Love.” Julianna Margulies, a take-no-prisoners attorney who defends rather than prosecutes (as most TV lawyers are wont to do) and has a rocky personal life, is as much the anti-“Shark” as she is the femmy “House.” Working against this promising show is its terrible time slot: 7 p.m. CT Mondays (Fox 4), for something better suited to the 9 o'clock hour. Won't it be great when everyone has TiVo?

WEDNESDAY

“Top Chef” returns at 9 p.m. CT on Bravo with a new season in a new location: Chicago, known to some as the Windy City but to those who live there as a diner's kind of town. (But apparently they go somewhere else for their sauce: KC Masterpiece is a sponsor this season.)

THURSDAY

Following in the path cleared by “Mythbusters” and that show hosted by Cliff from “Cheers” comes “Who Knew? With Marshall Brain” (7 p.m. CT, National Geographic). Here, the man behind HowStuffWorks.com explains such everyday phenomena as fireworks that burst exactly on cue with the music, mountain bikes made from Stealth bomber parts and the printing of currency.
