There's something to be said for knowing what your customers want and delivering, and while watching "Rizzoli & Isles" (10 tonight), I was struck by how thoroughly TNT the show is.

Besides having two strong, accomplished women at the center of it, the show has that same mix of grit and humor as "The Closer" and "Leverage" and "Saving Grace." And although the network stakes its claim with drama, characters are welcome on TNT too.

That's the other thing that struck me after viewing this very likable, fairly creepy first episode of "Rizzoli & Isles" -- it's a first episode that firmly lets us know who these characters are through the plot rather than through exposition like a lot of first episodes do. There's no starting out slow here; it comes out the gate with a crime that hits close to the characters.
