"Bottom Feeder" (6 p.m., SyFy): The always entertaining Tom Sizemore stars in this horror movie about a mutated monster that targets maintenance workers in tunnels. It's not clear whether Sizemore is the monster or a maintenance worker.

"Moments of Impact" (8 p.m., Discovery): Call it extreme marital therapy. A bickering couple gets thrown from their boat.

"The Real Housewives of Atlanta" (9 p.m., Bravo): For the premiere, you'll meet new housewive Kandi Burruss, a singer-songwriter who wrote TLC's "No Scrubs." But it's Sheree's jaw-dropping verbal altercation with her party planner that is not to be missed. You can thank me later.

"Law & Order" (9 p.m., WMAQ-Channel 5): Say goodbye to "The Listener," which is being replaced with "L&O" reruns like tonight's, about a child slave-trade ring.
