The end of May 2025 will see Netflix releasing the much anticipated final season of Big Mouth. This animated adult comedy follows a group of classmates whose experience with puberty and sexual attraction are manifested in the form of monsters who represent their baser instincts.
While the end of Big Mouth is notable for Netflix losing a popular series, it’s sure not the end of the genre. The adult animated genre has been popular for decades, and the advent of streaming has only made it more popular and more accessible. If you’re looking for something to fill the void left by Big Mouth, here’s where you can stream five adult animated shows that are very R-rated and sure to make you laugh, cry, and maybe cheer a little bit, too.
South Park (1997-Present)
Would it even be possible to discuss R-rated adult animation without mentioning the longest-running and most prominent of the genre? South Park wrote the book on adult animation, and it continues to add new chapters to this day. Though it premiered in 1997, everything about its lifespan—from its vulgar first episode accidentally being released on PS1 game discs to its recent films takings shots at everything from social media celebrities to weight loss drugs—has been about offering critical commentary about the world around us while being as shocking as possible. It remains a fan favorite to this day, with Season 27 set to premiere in July 2025, and regularly ranks as one of the greatest cartoons ever made,
The Boondocks (2005-2014)
Based on the hit comic strip of the same name, The Boondocks was a surprise hit on Cartoon Network as part of the Adult Swim lineup and became something of a cultural phenomenon. The show follows the Freemans, a Black family who moves from Chicago to the white suburb of Woodcrest. Today, The Boondocks is revered for its satirical humor built on examining social issues and relationships. While the series did stumble with its fourth and final season, which saw series creator Aaron McGruder step away due to scheduling issues, the show is still overall regarded as one of the best series of all time, animated or otherwise.
The Venture Bros. (2003-2018)
Another hit on Cartoon Network’s Adult Swim, The Venture Bros. serves as a loving parody of classic ‘60s cartoon Jonny Quest. The series is about the highly dysfunctional Venture family, including patriarch Rusty Venture, a child genius turned famous scientist whose morals are flimsy at best, and his twin sons (who are, in fact, clones), Hank and Dean. Aided by a bevvy of sidekicks and co-stars, including brawny bodyguard Brock Samson, the family finds themselves in misadventure after misadventure. The Venture Bros. enjoyed a healthy run on Adult Swim, producing seven seasons between 2003 and 2018. Additionally, the shock cancellation led to fan outcry, resulting in a series finale film, The Venture Bros.: Radiant is the Blood of the Baboon Heart, officially ending the series for good in 2023.
BoJack Horseman (2014-2020)
The first adult animated series produced for Netflix, BoJack Horseman follows the titular BoJack, a washed-up star of a ‘90s sitcom struggling with depression, alcoholism, and addiction. The show started as a pithy comedy taking shots at celebrity culture, but what it became in later seasons was one of the most thoughtful and introspective shows Netflix ever aired. And to balance all that out, BoJack Horseman still manages to be downright hilarious, thanks to its unique take on “Hollywoo,” filled with a mix of humans and humanoid-animals in a world as wondrous as it is down-to-Earth. BoJack is a rare series and easily one any fan of animation needs to watch.
Invincible (2021-Present)
One of the current crown jewels of Amazon‘s Prime Video service, Invincible adapts the classic comic book series of the same name by The Walking Dead creator Robert Kirkman. The series follows Mark Grayson, a teenager whose father is the Superman pastiche Omni-Man, as he discovers his own developing powers and becomes a superhero named Invincible. Like the comic before it, the animated series has become renowned for its down-to-Earth characters, shocking plot twists, and no-holds-barred, blood-soaked action. While the series has received some flack for its long production time and animation that pales in comparison to the stunning original comic book, it remains one of Prime Video’s most popular series.
