the Big Mouth cast settling into the next stage of their education, and the next stage of their lives, as they get a little older, a little wiser, and a lot more confused. I’m amazed that after eight seasons, the writers keep coming up with new and universally relatable facets of puberty and adolescence to explore.
Nick gets a growth spurt that instantly makes him more popular. Jessi’s mental health struggles are symbolized through the Depression Kitty. The show explores the troubling notion that modern kids are learning the wrong lessons about sex from watching pornography. Now that they’re surrounded by sexually active high schoolers, our characters grow insecure about their lack of experience. This series has always been a keenly observed, deeply comionate portrayal of the chaos of puberty disguised as a raunchy cartoon. Its gross-out humor makes Family Guy look tame, but it’s a surprisingly important show, and season 8 hammers that home.
The writers keep coming up with fun storylines that reveal new sides of the characters and put strain on their relationships. Every character breaks off and s their own clique in high school: Matthew falls in with the theater kids, Jessi falls in with the stoners, and Andrew and Missy the robotics club. Nick goes to a different high school and becomes enamored with a new best friend, also called Andrew, making the original Andrew jealous. In one of the season’s funniest storylines, Jay becomes an overinvolved, overprotective parent after being given a melon to look after as a school project.
Big Mouth's Voice Cast Continues To Shine In Season 8
I'll Miss These Incredible Voice Actors & Their Lovable Characters
Big Mouth’s voice cast continues to shine in its final season, and it’s a big reason why I’ll miss the show so much. Nick Kroll anchors the show with his everyman turn as Nick using his own voice, but he also displays his impressive versatility as a voice actor by disappearing into roles like Lola, Coach Steve, and Maurice the Hormone Monster. Jason Mantzoukas nails Jay’s unhinged bravado, Ayo Edebiri nails Missy’s endearingly giddy geekiness, and John Mulaney perfectly captures Andrew’s painful awkwardness and constant state of panic.

10 Big Mouth Episodes That Tackled Serious Topics
Big Mouth has proven it isn’t afraid to tackle serious topics that affect young viewers, and these episodes are especially important in that regard.
Big Mouth season 8 also has some great stunt castings with its guest stars. Steve Buscemi plays a sneaky cat named after his Reservoir Dogs character, Mr. Pink. Missy’s celebrity crush, Nathan Fillion, plays her love interest, Nate. And that’s just one way the show is wonderfully meta. Big Mouth has always been self-aware, and it leans into it more than ever in its final outing. Nick and Andrew mention being “redrawn” as their bodies change. The cops report a “possible season 1 payoff in progress.” Every wink to the audience is warmly received.
Big Mouth is available to stream on Netflix.
Big Mouth is still hilariously gross in its final season — one shocking extended sequence sees Nick repeatedly masturbating into a Minions t-shirt and making lewd sexual remarks about Kevin and Stuart — but it’s still genuinely educational, too. The series explains how puberty, hormones, and menstruation work to an audience that might still be confused by it. One memorable episode takes a magical musical tour through the human anatomy with testosterone depicted as a gruff, musclebound alpha male and estrogen depicted as Mr. DNA from Jurassic Park.
Big Mouth Uses Gross-Out Humor To Mask A Nuanced Sex-Ed Discussion
The Show Trojan-Horses Its Exploration Of Underdiscussed Subjects Through Its Crass Cartoon Comedy
In its final season, Big Mouth does what it’s always done best: using gross-out humor and cartoon craziness to mask a thoughtful exploration of important topics surrounding adolescence and sexuality. This is a show where Andrew will enthusiastically sing a song about all the mundane household items that turn him on, but it’s also a show where Jessi can have a nuanced discussion about consent.

The perfectly pitched series finale combines nostalgia, embodied by living flashbacks, with anxiety about the future, symbolized by a looming white void. Although the show concludes on a crass punchline, Big Mouth’s final moments are oddly heartwarming. It’s the perfect note to end this series on: crass, but heartwarming.
