Six years after wrapping his Emmy-winning sitcom “Schitt’s Creek,” Dan Levy is back delivering more laughs with his latest TV offering, “Big Mistakes,” a mixed bag of chaos, dysfunction and a ton of humor.

The high-stakes comedy thriller — co-created, executive-produced, showrun by and starring Levy — is a messy but hilarious family saga that, while it doesn’t always land its plot, has a delightful cast that still makes the series a pretty entertaining watch.

Leading the comical ensemble is Levy as Nicky, the openly gay pastor of Glenview Community Church, who dates his boyfriend in secret to avoid offending his congregation (they prefer him “non-practicing”). Opposite him is Taylor Ortega as Nicky’s sister, Morgan, a public school teacher who returns home after an unsuccessful attempt at launching an acting career in New York City. Back in town, she reunites with her clingy high school sweetheart, Max (Jack Innanen).

“Big Mistakes” also stars Abby Quinn, Elizabeth Perkins, Mark Ivanir, Ilia Volok, Jacob Gutierrez, Joe Barbara and Darren Goldstein.

The show kicks off with Nicky and Morgan’s grandmother on her deathbed, as their high-strung mother, Linda (Laurie Metcalf), tries to make her last days as comfortable as possible. She suggests that the siblings get their Nonna something cheap and nostalgic to cherish before she passes away, so they go to the store to buy her some jewelry. When the tough store clerk (Boran Kuzum) refuses to sell Morgan a particular necklace, she steals it, not knowing it’s worth a ton.

This misguided theft is one of many “big mistakes” that unknowingly lure Morgan and Nicky into the world of organized crime, forcing them to work for a group of dangerous gangsters. It’s a far-fetched storyline that escalates rather quickly early on in the show, but it doesn’t become a drag across its eight bingeable half-hour episodes.

Even when the crime antics feel disjointed and flat, the show’s biggest strength lies in Levy and Ortega’s chemistry. Their hysterical banter and frantic sibling dynamic are what will keep you invested, wanting to know what outlandish situation they’ll stumble into next.

As a pair, Levy and Ortega are comedy gold. And the twist their characters leave viewers with at the end of the season is enough to at least want to see where “Big Mistakes” goes next, should it get renewed. According to Levy, he already has a plan for a five-season arc.

“I know exactly where it’s going,” he told The Wrap, “and so I really hope people watch it so that we can keep telling these stories, because there’s a lot more to come.”

All episodes of “Big Mistakes” are streaming now on Netflix.
