SEASON PREMIERE: The news broke recently that Veep series creator Armando Iannucci has left the series after four seasons – replaced by David Mandel, who worked with series star Julia Louis-Dreyfus on Seinfeld, and also was an executive producer, writer and director on Curb Your Enthusiasm. Here’s hoping the transition will be a smooth one, because the first Season 4 episodes, beginning with tonight’s premiere showing Louis-Dreyfus’ Selina Meyer settling in as President of the United States, may be this series’ very best yet. Tonight’s Veep crackles with wit in every scene, with the series regulars – Anna Chlumsky, Tony Hale, Gary Cole and company – scoring with one perfectly delivered line of dialogue after another. “This thing is getting way too big,” one character says of a suddenly escalating crisis. “It’s like my mom’s cat.”
