Continuing its quest for total rerun domination, Law & Order (8 p.m., TNT) begins airing syndicated reruns on Tuesdays on TNT, in addition to round-the-clock on A&E. The TNT run kicks off with the one where Julia Roberts drops by to play footsie with Ben Bratt. The new sitcom Kristin (8:30 p.m., NBC) stars Broadway baby Kristin Chenoweth as a sunny gal from Oklahoma who goes to New York to be an actress, but ends up working as a personal assistant to a womanizing real-estate developer (Jon Tenney). On a rerun of NYPD Blue (10 p.m., ABC), Diane and Danny have some awkward moments, Denby gives Diane a false lead and Andy gets the word on Theo's condition. It seemed a little odd that Rick Schroder's Danny Sorenson didn't appear in the "Blue" season finale (he went missing after going on a bender and having a stripper turn up dead in his apartment). But now it all makes sense: Schroder announced over the weekend that he was following in the footsteps of David Caruso, Amy Brenneman, Jimmy Smits, Sharon Lawrence, Gail O'Grady, Nicholas Turturro, James McDaniel and Kim Delaney and leaving the show. At this point, Dennis Franz has got to be wondering, "Was it something I said?" Frontline (10 p.m., PBS, check local listings) presents "Blackout," a report on the energy crisis in California, coming soon to a deregulated state near you.
There's no "Buffy" tonight, but you can still see Sarah Michelle Gellar on the WB in I Know What You Did Last Summer (8 p.m., WB). Those with short attention spans can skip ahead to the next film in the series, I Still Know What You Did Last Summer (9 p.m., USA). Court TV's Safety Challenge 2001 (10 p.m., Court TV) quizzes viewers on crime survival strategies, using dramatizations and interviews with experts. ABC News correspondent Jack Ford hosts.
