Created by Dan Levy and Rachel Sennott. Starring Dan Levy, Taylor Ortega, Laurie Metcalf, Abby Quinn, and Fahim Anwar.

Big Mistakes began as a dark comedy about two siblings making increasingly bad decisions that gradually evolved into something much darker.

By the end, the danger feels more real. The consequences become more serious. And the laughs are noticeably harder to find.

The increasingly elaborate crime plot, escalating danger, twists, and revelations all help keep the story moving, but the real engine of the series remains the relationship between Nicky and Morgan.

Dan Levy and Taylor Ortega have the kind of chemistry that makes you believe these two genuinely drive each other completely insane. Every argument feels authentic. Every moment of support feels earned. And when their decisions become increasingly frustrating, you still find yourself fully invested in seeing how they’re going to get out of the mess they’ve created.

Underneath all the crime, chaos, and absurdity, Big Mistakes is really about two people who have spent much of their lives avoiding difficult choices.

Nicky spends much of the season hiding from the life he wants. Morgan often feels like she’s trapped in hers. Neither seems particularly good at taking control of their future. Instead, they spend much of the season reacting to events that happen to them.

Which raises an interesting question.

Is this a show about hilarious absurdities like cocaine hidden in bull testicles?

Or is it a show about two people so paralyzed by fear, insecurity, and indecision that they accidentally stumble into a life of crime?

The answer is probably both.

The supporting cast continues to be one of the show’s strengths. Laurie Metcalf remains one of television’s most reliable performers. Every scene she appears in feels sharper, funnier, and more confident.

The finale also gives Abbey Quinn an opportunity to reveal a few additional layers. For much of the season, she largely functions as the family’s golden child. By the end, it feels like the writers are beginning to recognize there are interesting stories to tell with her as well, which could pay dividends if the show returns.

The season delivers a few genuinely surprising twists and reveals, though not every storyline works equally well. A handful of narrative threads feel underdeveloped, and some developments land more effectively than others.

The finale leaves Nicky and Morgan in a far more dangerous position than where they started, pushing the series into darker territory than I expected when it began.

That shift doesn’t always feel seamless, but it does make me curious about what comes next.

The cast is strong. The sibling dynamic remains compelling. And the show continues to find clever ways to escalate the trouble surrounding its characters.

I’m still not entirely sure where Big Mistakes is headed next.

But I’m going to keep watching.

Verdict: I’m On Board
