“Southern Belles: Louisville” (9 p.m., SoapNet) is not the most original title in the world. But the truth-in-packaging version, “The UnReal Non-Housewives of Louisville” just didn’t have the right ring.

“Belles” walks a fine line between Southern gentility and the nouveau-riche vulgarity of the “Real Housewives” franchise. Only two (or three) of the “Belles” inspire real hatred at first sight.

Shea is a self-professed “daddy’s girl” who complains about her fiancé, a mere mortal with a human-scale salary, and the fact that he hasn’t mortgaged his soul to buy her a ring to match her ego.

Kellie is a twice-divorced 32-year-old who moans about her reduced circumstances. She now resides in a house that “could fit into the guest house at my old house.” Julie used to be one of the hottest models in town, but neither her inflated self-image nor her career stands to survive her 35th birthday.

Hadley claims to be a Ph.D. candidate (you don’t see too many of those on “The Real Housewives of New Jersey”!) who has put her brain in escrow for the duration of this program. Right now, she’s specializing in dating and the pursuit of fun.

Emily eschewed the daddy’s little princess route and defied her rich father’s wishes for her to run his business.

She has opted to become a journalist instead, and seems resigned to earning a meager salary to pursue her dreams. Dad thinks this is a “nightmare.”

She seems like the only “Belle” with a head on her shoulders. As a local TV reporter, she knows the value of getting her face on television.

If it weren’t for the advantageous exposure that “Belles” provides, I would imagine that Emily would ditch these losers.

• Two summer staples return tonight. Cat Deeley hosts “So You Think You Can Dance” (7 p.m., Fox) as it enters its fifth season. While not as popular as the just-concluded “Dancing with the Stars,” it is the superior dancing showcase because it puts the accent on talent.

It’s also the place to see more contemporary modes of performance, from hip-hop to Krumping.

Now in its second season, “Crime 360” (9 p.m., A&E) offers all of the forensic sleuthing of “CSI” but without the Vegas locales or kinky subplots.

In fact, the real pleasure of “360” is its no-nonsense police work in unglamorous settings. Episode 1 takes place in Ohio, somewhere between Cleveland and Ashtabula.

But these cops employ a wide range of techniques and gadgetry. They also speak in a gentle vernacular (“if you find something, give me a jingle”) lost to TV script writers, except those straining for “Fargo”-like irony.

Tonight’s season finales

• Tennis champ Billie Jean King guest stars on a two-hour “Ugly Betty” (7 p.m., ABC).

• Gang warfare knocks on the doors of Dodger Stadium on “Southland” (9 p.m., NBC).

Tonight’s other highlights

• Twisters touch down in Camden on “My Name is Earl” (7 p.m., NBC).

• The murder of a mother and child seem linked to a decade-old crime on “CSI” (8 p.m., CBS).

• On two episodes of “30 Rock” (NBC), an Oprah encounter (7:30 p.m.), Liz meets a fascinating recluse (Steve Martin) (8:30 p.m.).

• A love triangle erupts into a hostage crisis on “Flashpoint” (9 p.m., CBS).

Cult choice

A serious musician (Don Ameche) has his work stolen to form a Broadway revue in the 1944 musical “Greenwich Village” (7 p.m., TCM) starring Carmen Miranda.
