Critic's corner

9 p.m., TNT
After a nine-hour marathon of repeats beginning at noon, the show is back for a fourth season. Which, in the middle of a pretty fallow TV summer, is a very good thing indeed. Of course, "The Closer" rests on Kyra Sedgwick's shoulders as Deputy Police Chief Brenda Leigh Johnson, the lady with the unique Southern accent. But the show is also a consistently good police procedural, with cases that are a lot smarter than those the "Law & Order" shows deliver these days.

10 p.m., Discovery Channel
Mickey! Minnie! Nooo!

8 p.m., Channel 5
Reality couples don't get cold feet. They get merger apprehension.

10 p.m., MTV
And then they'll search for Jakes?

8 p.m., Planet Green
Celebrity chef and failed sitcom star Emeril Lagasse hosts this new series about how to make healthy, organic, and eco-friendly dishes. Frankly, the show sounds dangerously infomercial-like, since it will be shot on location at a particular market whose name I've wholly decided not to mention here. Emeril will be making meatless meatloafs and flourless angel food cakes.

8 p.m., TCM
Bill Murray talks all about his divorce. Not.

10 p.m., TNT
Holy Holly.
