Mrs. Warmth

We recently lost Don Rickles, but insult comedy lives on, thanks to Selina Meyer. In the new season of “Veep,” Julia Louis-Dreyfus proves she’s worthy of her basketful of Emmys by putting her (former) presidential seal on one withering zinger after another. “The inside of your mouth looks like a Haitian port-a-potty” is just one of the politically incorrect lines that would have made Mr. Warmth howl.

Slow death

After the success of “Serial” and “Making a Murderer,” it might seem that every real-life whodunit deserves an epic presentation. “Killing Richard Glossip” tests that belief. While there’s plenty of intrigue in the journalism-driven investigation of the murder of an Oklahoma City motel owner, it’s hard to justify the four-hour running time, especially since the report ends with no resolution. Glossip’s case seems to merit a further probe in the courtroom, but not cable TV.

McGregor, Minnesota

Billy Bob Thornton and Kirsten Dunst upped their Hollywood cred by going Minnesotan. Now it’s Ewan McGregor’s turn. The English actor plays warring brothers in the third season of “Fargo,” set in Eden Valley, Eden Prairie and St. Cloud. Based on the first hour, doubling down will probably pay off. He’s terrific. To learn more about how McGregor took on one of the greatest challenges of his career, see Tuesday’s Variety section.
