True Blood (9pm, HBO) - The gore is getting to me, folks. I'm about to bow out of this one. First there was Bill's violent, neck-twisting sex scene with Lorena (left), and then last week's vicious feeding scene in the limo. Yuk. I may not have the stomach for the gore-porn that has become "True Blood," but plenty of other people do, so here's what's happening tonight: Sookie and Alcide seek counsel from an expert to deal with Russell's werewolves, Lafayette learns a lesson from Jesus, and Eric's thirst for revenge intensifies with a reminder from his past.

In the premiere episode of this new series, we meet a 73-year-old former model who is dating a 33-year-old father of two. In the 10:30 episode, scientists test the claims of a woman who insists she can think herself into ... you'll have to tune in to see. 

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.

The Gates (10pm, ABC) - Another summer series premiere from ABC. In this one, a former city cop takes a job as police chief in the suburbs and works a missing persons case that has him investigating his new neighbors. It's darker than the silly ABC promos you've seen.

Treme (10pm, HBO) - It's the 90-minute first season finale of David Simon's exceptional series set in post-Katrina New Orleans. Tonight's finale comes together in a devastatingly beautiful way. And the cast shines, from the Big Chief Clarke Peters (right) to Khandi Alexander, John Goodman, Wendell Pierce, Steve Zahn, and Melissa Leo. Don't miss.

The Real L-Word (10pm, Showtime) - The premiere of a new reality series that follows six lesbians in Los Angeles.

American Idol (9pm, Fox) - Billed as a "Road to Hollywood" installment, this episode boasts guest judges Kristen Chenoweth, Joe Jonas, Neil Patrick Harris, Victoria Beckham, Mary J. Blige, Katy Perry, and Avril Lavigne. Must be a clip show of moments from the preliminary auditions.

Law & Order: Special Victims Unit (9pm, NBC) - Naveen Andrews ("Lost") is a detective from the Special Frauds unit accused of stalking a woman whose parents were murdered. 

Leverage (10pm, TNT) -  I think it's a requirement that at least once per show per season, someone must "infiltrate the world of high fashion" to solve a murder or save workers from slaveshop conditions. "Leverage" opens its second season tonight with such an episode.

Leverage (9pm, TNT) - TNT ordered two extra episodes of this drama for their summer season, so you'll get your "Leverage" fix until September 9. Griffin Dunne and Will Wheaton guest star tonight and the episode is directed by Dean Devlin, the show's producer.

Top Chef: Las Vegas (10pm, Bravo) - It's too early to pick a clear favorite, but last week's premiere was enough to tell us that we are definitely not pulling for Michael Isabella (right), an obnoxious Jersey boy working out of D.C.  Self-confidence is not a problem for this guy, but chauvinism is. The show has some extremely talented (and interesting) chefs this season, including competing brothers from Maryland and Ron Duprat, who spent 27 days at sea traveling from Haiti to the U.S. Last week, Ron didn't seem to understand the meaning of the word "vice," but he cooks a mean sea bass. Tonight, the men are pitted against the women, as the groups vie to cater a poolside bachelor-and-bachelorette party. Chef Todd English is the guest judge.
