Teenage friends find their lives upended by the wonders and horrors of puberty in this edgy comedy from real-life pals Nick Kroll and Andrew Goldberg.
Netflix’s Big Mouth didn’t just push boundaries—it bulldozed them. The adult animated series, which ran for eight seasons from 2017 to 2025, turned the awkward horrors of puberty into a surreal, often outrageous comedy. But behind the Hormone Monsters and talking penises, the show’s creators were navigating their own minefield of controversies, creative limits, and personal inspirations.
Big Mouth wasn’t just a wild idea—it was deeply personal. Co-creator Nick Kroll and his childhood best friend, Andrew Goldberg, drew heavily from their own middle-school traumas to craft the show’s cringe-worthy yet relatable storylines. The series, which followed a group of pre-teens navigating puberty with the help (and hindrance) of Hormone Monsters, was built on "embarrassing real-life tales" from Kroll and Goldberg’s past . While the show’s absurdity—think talking genitals and hormone-fueled meltdowns—was exaggerated for comedy, its emotional core was rooted in real experiences.
For all its success, Big Mouth wasn’t without backlash. Season 3, which premiered in 2019, faced accusations of biphobia and transphobia, forcing the creators to acknowledge they had "missed the mark" . The show’s willingness to tackle taboo topics often walked a fine line between satire and insensitivity, and not every joke landed.
Even Netflix, known for its anything-goes approach to content, occasionally reined in the show’s excesses. Kroll revealed that the streaming giant had vetoed some of the most over-the-top scenes, proving that even Big Mouth had limits . Still, the show’s ability to shock and amuse kept it running for nearly a decade.
By 2025, Big Mouth had run its course. Kroll admitted that dragging the show out indefinitely would have been a "disservice" to its story. The series had always been about the chaos of adolescence, and stretching it beyond its natural lifespan risked losing its edge . The decision to end after eight seasons wasn’t just practical—it was a rare moment of restraint in an era of endless reboots.
Despite its controversies, Big Mouth carved out a unique space in adult animation. It blended raunchy humor with genuine emotional beats, making it a standout in Netflix’s lineup. The show’s voice cast—including Kroll, John Mulaney, and Maya Rudolph—brought its bizarre characters to life, while its willingness to tackle uncomfortable topics kept audiences hooked.
Whether it was the Hormone Monsters’ antics or the show’s unflinching look at puberty, Big Mouth never shied away from the messy, awkward truth of growing up. And in the end, that’s what made it so unforgettable.
