Is it curtains for Donald Glover’s beloved and much awarded FX series, “Atlanta”?

Last night came the season finale of the show’s second season, and there is no renewal in place. Fans started freaking out as cryptic messages on Twitter seemed to indicate we’d watched the end of the whole project.

It wouldn’t be a shock. Glover stars as a young Lando Calrissian in the new “Star Wars” movie. His new single/video, “This is America,” considered a tour de force, is number 1. His recording star alter ego, Childish Gambino, will issue a new album this year.

Indeed, Glover’s stock is rising fast. With “Atlanta,” he made a perfect series. He could always pick it up again, like Larry David with “Curb Your Enthusiasm.” Or he could just let it go, as Amy Schumer–whose own star was in ascent with the movie, “Trainwreck.” She just let it go.

FX has not made an official announcement.

“Atlanta,” however, is not a big hit on FX. The fans (I count myself among them) are a discerning lot. According to tvseriesfinale.com, “Atlanta” ranks 7 out of 13 among FX scripted shows.

UPDATE: Last night’s episode scored only 553,000 viewers, down from 694,000 a week ago– more than 20% drop. Ouch!

“Law & Order: SVU” has its hard core fans. So they will be thrilled to know that their show, starring Mariska Hargitay, has been renewed for its 20th season.

This means they’ve tied the run of the original “Law & Order,” which ran 20 seasons before getting abruptly cancelled after ratings fell out in the final season.

“SVU” is planning a cliffhanger season finale for May 22nd, by the way, so they’d better be coming back this fall!

What a tribute to Hargitay, who assumed the starring role when Chris Meloni left several years ago. Her mother, the late great star Jayne Mansfield, must be smiling in heaven. Mansfield’s life was cut short in a terrible car accident in 1967. Mariska was just three years old. She’s gone on to be such a success on “SVU,” as well as being a tireless advocate for women as a documentary producer.

NBC also renewed producer Dick Wolf’s three Chicago shows– police, fire and post office. (Just kidding.) It’s actually kind of amazing that Wolf had all those New York shows that were hits, then changed the locale to Chicago and had hits all over again.

Today, Wolf also formally announces his branching out to CBS, as well, where his new “FBI” rolls out in the fall with 13 episodes. Jeremy Sisto, an alum of “Law & Order” and “Six Feet Under,” stars with hot newcomer Zeeko Zaki as the lead FBI agent. Zaki is going to be The New Guy this fall who everyone’s talking about. His six foot five and of Egyptian descent although raised in the US.

Bringing on Muslim neighbors didn’t do much for the “Roseanne” ratings last night. They were pretty much the same as last week, with 10.1 million viewers tuning in. The good news is that there wasn’t a huge drop off. But “Roseanne” did lose 300,000 viewers from last week, and that’s significant.

Still, for the night, “Roseanne” was not the biggest event. That honor went to “NCIS” with nearly 15 million people tuning in for the season finale and exit of two characters. So five million more people went for Pauley Perrette’s goodbye over Roseanne and co.

“Bull” on CBS followed with 11.8 million viewers, pushing “Roseanne” to third place for the night.

“NCIS” fans are crying this morning over the exit of actress Pauley Perrette after 15 years. She played forensic scientist Abby Scuito with verve and humor and was the de factor leading lady of the series.

There was no reason Perrette should leave. and she’s never given an adequate explanation. But last night’s episode was meant for reading between the lines. Perrette and the series’ difficult leading man, Mark Harmon, never shared a scene or spoke to each other for the whole hour.

NCIS Scores Huge Numbers for Finale

This was cleverly accomplished. Right until the end, Abby and Harmon’s Gibbs weren’t even in the show together. For the final moments, the producers cut together two close ups as the characters waved goodbye in sign language.

Otherwise, Abby and Gibbs had no contact with each other. She told her pals at NCIS she was leaving and hugged them all– except Gibbs, who wasn’t even in the room. Think about it: Abby was shot and Gibbs didn’t even visit her in the hospital.

Years ago, when Lauren Holly was the female star of the show, sources told me in detail how badly Harmon treated her. She was forced to leave the show. Perrette has been very diplomatic about her exit. She hasn’t said a word about Harmon. But silence speaks volumes. She’s posted a lot of photos and Tweets to other fellow stars of the show, but none about or with Harmon.

In addition to Abby’s exit, another character left “NCIS” last night, the MI6 agent Clayton Reeves. He was played by so well by black British actor Duane Henry. So, “NCIS” managed to shed a woman and a black man. Was this part of CBS’s diversity program? On a network that has one female (Tea Leoni) and one black dramatic lead (Shemar Moore) for its series, this news should be pretty upsetting.
