In all these years of mob films and TV shows, mobsters named in dramatic pieces and so on, there has never been one named Sinatra.*

Until tonight.

“Law & Order Organized Crime” featured a mob family named Sinatra. Father Manfredi, played by Chazz Palminteri, was killed off at the end of the first episode. His son, Richard, played by Dylan McDermott, takes the name Wheatley. He will be a regular character. But the name Sinatra remains.

Until tonight, the only Sinatras were the family of Frank, the most famous popular singer of all time. During Frank’s lifetime he battled the idea that he was mobbed up or had mob associates. Time was a factor in getting rid of that notion, right or wrong, leaving just Frank’s mellifluous voice and his occasional movie roles as his legacy.

But now it seems we’re going to get a weekly dose of the Sinatra crime family on “Organized Crime,” a show very unlike other “Law & Order” installments. So far, “Organized Crime” seems like it will be about Elliot Stabler seeking justice for the killing of his wife, Kathy. There’s very little law, or order. Or ensemble opportunities, unless the focus changes. This is Elliot Stabler’s show.

Getting rid of Kathy was essential. Elliot needed something to avenge, hence her murder. Also, the sexual chemistry between Chris Meloni and Marisa Hargitay is still there. Benson and Stabler are headed to something, probably during May sweeps. In the morning we’ll see how the ratings were. My guess is they were good.

As for Sinatra, there are other Sinatras out there in the world. But the name has the same resonance as Ketchup or Kleenex. This was an odd choice for the Dick Wolf crowd. We’ll see if Nancy or Tina, Frank’s daughters, have anything to say about it.

I don’t know how much fans already know about tonight’s Stabler-Benson reunion on “Law & Order SVU.”

But I did ask an insider with the show what they could tell me that wouldn’t be categorized as a spoiler.

For what it’s worth, here’s what I got:

Director Juan Campanella directed tonight’s show. He goes back to Season 1 in 2000 with Mariska Hargitay and Chris Meloni in the the first season, so they had a reunion, too. Campanella left the show in 2010 and didn’t return until this past fall.

The first time you’ll see Elliot Stabler in “SVU” tonight is a bar scene with Fin, aka Ice T.

Swayne “The Rock” Johnson is a big movie star, a huge draw in action films and light comedies when there is a box office.

He hasn’t had a failure in some time, but NBC may be handing him his first defeat shortly. “Young Rock,” the prime time series about The Rock growing up, is a bust in the ratings.

Last night, “Young Rock” in its six outing fell by 12.9 percent in total audience and almost 20% in the key demo, 18- 49, the audience it needs to attract.

Indeed, “Young Rock” has dropped 50% since its premiere six weeks ago.

Nothing about The Rock’s movie popularity is translating to the TV show.

And it’s a bigger problem than just The Rock. NBC put “Young Rock” in at 8pm to draw an audience at 8:30 for “SNL” star Kenan Thompson’s “Kenan” sitcom. This show is so awful, and also has no audience. Last night “Young Rock” drew 2.5 million viewers. Then “Kenan” got squashed at 1.9 million.

“Kenan” is the wrong setting for Thompson, despite a strong cast. The writing and premise are terrible. Kenan needs to host a variety show. He is so talented, and deserves to be a star. But this sitcom thing is not for him. He’s bound and constrained. Let him just be Kenan. And whoever thought Don Johnson should be in this needs to reconsider their career. Yikes.

As for The Rock, a cancellation for “Young Rock” will just be brushed off. But if the show drops below 2.5 I don’t see how or why NBC would keep it on. There are five episodes left in the original order of 11.
