You can see it in the easy bromance between Geoff Stults and Michael Clarke Duncan. You can see it in the assortment of oddball Florida swamp characters. You can tell by the fact that suddenly you're being treated to a John Fogerty jam. "The Finder" (Fox, 9 tonight) has potential.

So even though this first episode doesn't quite gel, I have a feeling we shouldn't give up on this show.

If you didn't see the "Bones" episode that introduced the characters, "The Finder" is Walter Sherman (Stults), a war vet with a brain injury that gives him the ability, and the unceasing desire, to find things. His best bud Leo (Duncan) is kind of his manager, but he also has this wise man protector thing going too. They live and hang out at a bar called the Ends of the Earth on Looking Glass Key, along with Willa Monday (Maddie Hasson), a young grifter, who may or may not be reforming her ways. They've also got a Deputy U.S. Marshal friend (Mercedes Masohn).

Person of Interest (9pm, CBS) - The episode information simply says "Reese and Finch involve Carter in a case," so I guess that means Reese survived his gunshot wounds from the previous episode...

Have You Heard from Johannesburg (2am, UNC-TV) - This is a five-part Independent Lens series tracing the anti-Apartheid movement, which UNC-TV is not only showing at bizarre times but apparently also a little out of order.
