Pop star Adele sang a medley of her hits as part of a sketch tonight on “Saturday Night Live.” She was totally charming as host even though she said in the closing bit that her appearance was “totally random.” She was charming and funny and looked great.

More importantly, she did admit that “my album’s not finihsed.” Next month will be five years since her last album release. Still, it was great to see her. My guess is the ratings will be very high when the numbers come in later today.

Maya Rudolph didn’t play Kamala Harris, but she was great in several sketches. She is a treasure. Ditto Kate McKinnon. Really missing Cecily Strong and Aidy Bryant.

Jim Carrey is still not making it as Biden. Alec Baldwin as Trump was, as usual, hilarious although he seemed a bit off.

HER Music sang two songs. The second one, “Hold On,” was excellent. The video is below Adele’s followed by a link.

I don’t mean to minimize “The Undoing,” a taut mystery mini-series starring Nicole Kidman and Hugh Grant. I’ve watched 5 episodes but not the ending yet. HBO PR left us with a cliffhanger after that 5th episode. But before we talk about the cinematic qualities, first we must discuss the overcoats: I want them, all of them, men’s and women’s. The costumes, the furnishings, everything. These characters are RICH, old school New York wealthy, very subtle, and wow, who lives like this? It’s dazzling in its elegance.

So okay. Nicole is a shrink named Grace, whose father, played by Donald Sutherland, is a New York lion. Wall Street? Banking? Real estate? He has a great mane of white hair, a deep resonant voice, and he plays classical piano in his football field sized living room. He has a staff, too, maids galore! I want him to adopt me. (He must live at like 730 Park or something. We are in the stratosphere.)

Grace’s husband, Jonathan (Hugh Grant, just great) is a pediatric oncologist. Admired, front page of New York magazine, that sort of thing. They have a perfect 12 year old played by Noah Jupe who goes to a $50,000 a year Upper East Side school and plays the violin almost as well as Itzhak Perlman. Everyone has a car and a driver. Grace’s BFF is a corporate lawyer played by Lily Rabe, who really needs to a Star by now.

The Undoing is based on a novel called “You Should Have Known” by Jean Hanff Korelitz. Susanne Bier directed the mini series based on a screenplay by David E. Kelley, who gave us “Private Practice” on TV and was once a lawyer so he was attracted to the murder mystery here and its legal ramifications. In short, Jonathan’s mistress is killed and he’s accused. But it’s unclear if he did it. The way Kelley writes it, everyone could be a suspect including the waiters (one of whom worked at Elaine’s for real!).

The screenplay is so sophisticated that they even named a sub minor character after the philanthropist Rebekah Harkness, who was married to the heir to Standard Oil and actually lived at 730 Park. Someone here did their research.

Did Jonathan kill the mistress, who by  the way he also fathered a child with? I don’t know yet. I would like to. All I know is this mini-series is done right. I don’t get the reviewers who didn’t think it was mysterious enough; it was for me. Maybe it could have been done in five episodes, but what’s the difference?

Nicole Kidman gives an Emmy worthy performance. She’s radiant and funny and direct and is a movie star who’s happened into a miniseries. Her performance, the character, and the whole thing are quite different than “Big Little Lies,” very different in fact. Don’t make the mistake that this is the same deal. It’s far from it. Kidman played a victim in that series. In this one, she’s very much in charge of her life and maybe everyone else’s. I liked seeing her this way. Kidman’s closeups are worth studying. She’s really at the tip top of her game. She is endlessly watchable.

Hugh Grant has not aged well. He’s three years younger than me and I don’t know, I guess he had a really good time on the way. But he’s turned into a much stronger actor, very powerful dramatically. Getting craggy has only helped him. And Donald Sutherland, well, he can read the dictionary and get awards.

Besides Lily Rabe, we have really good supporting work from Noah Jupe, Edgar Ramirez, and Noma Dumezweni, who Shonda Rhimes should be writing a series for right now. (She’s my new Aisha Hinds, a find, if you see.)

The whole Bier tone is very “The Night Of,” which lifts “The Undoing” well beyond the usual fare, and Bier’s own masterpiece, “The Night Manager.” Don’t be afraid of enjoying a series for once, dig the decadence, and please, someone tell me how to get Hugh’s top coat. (I love that he wears it on the prison bus. I thought he’d be mugged.)

A plus entertainment.

Maybe ABC wants to give Roseanne Barr the last laugh after all.

The network moved “The Conners” from Tuesday to Wednesday this season, aired the opener at 9pm instead of 8pm, and lost a sizeable chunk of its audience.

Over 20 percent of “The Conners” fans from last season didn’t show up for the Season 3 premiere on Wednesday. It was the wrong night and the wrong time. For some reason, ABC put on back to back half hours of “The Goldbergs” as the lead in for “The Conners.” The latter show had been ABC’s strongest comedy hit on Tuesdays at 8pm. So, of course, they moved the “Roseanne” spin off to see if they could kill it.

All of this changing schedule has to do with having “Dancing with the Stars” and “The Bachelorette” on air at the same time. They used to alternate on Mondays at 8. But with the two shows on, one had to move to Tuesdays. So ABC sacrificed “The Conners.” Last spring’s season finale had 6 million viewers. Wednesday night’s premiere brought 4.9 million.

You could say baseball interfered, with the World Series on Fox. But really, there is no cross over or commonality between those audiences unless Roseanne herself was singing the national anthem.

ABC had better move “The Conners” back to Tuesdays at 8pm. No one at network TV has ever subscribed to the adage, If ain’t broke, don’t fix it. They might give that a try.
