The screenplay is based on a four-part New Yorker short story called Sell-Out by Simon Rich. That piece of writing along with other short stories earned him a reputation as a modern-day PG Wodehouse, not to mention being SNL’s youngest ever writer and polishing scripts for Pixar. Rich’s writing is sharp, often high-concept, and very, very funny. But the story has lost some of its zing in translating to the big screen, even with Rich on screenwriting duties and Rogan as the lead.
Rogen plays Herschel Greenbaum, a Jewish ditch digger, forced to flee his homeland with his wife Sarah (Sarah Snook) when a murderous gang of "Jew-hungry Cossacks" go on the rampage. They head to New York where Herschel finds work killing rats in a Williamsburg pickle factory, and Sarah becomes pregnant. Then disaster strikes, and Herschel is trapped in a vat of pickles where he is preserved until waking up in Brooklyn in the 21st Century. It’s here he meets Ben (also Rogen), his last surviving descendant, who works as a freelance app developer, dresses like he maxed out his credit card in Urban Outfitters and has a fridge full of kombucha. 
When Herschel’s pride is wounded by Ben’s rejection of family values, he decides to set up a pickle business to prove to Ben that family must come first. Ben is less than pleased when the pickle business is a big hit, so sets about sabotaging Herschel’s plans.
A lot of the laughs rely on the culture clash between Ben and Herschel. It’s an old-fashioned Hollywood trick employed in '80s comedies like Coming to America or Back to the Future, but it’s still effective. Here the jokes are down to Herschel’s reactions to the modern world, including discovering Twitter, and essentially becoming a beardy-Trump in a worker’s cap.
Ben’s character is relatively thin, and in the film’s second half Herschel becomes little more than a canvas to explore cancel culture, social media, and fashion fads. The film seems to want to have its pickle and eat it, praising some traditional values, but not condemning others, in a film that’s too frothy to handle such a debate.
American Pickle might be hoisted by its own silliness, but it’s full of cracking one-liners, a fun concept, and Rogen holds it all together.
