History YMMV / BigMouth

** HilariousInHindsight: In his namesake episode, The Shame Wizard calls Andrew 'ireedeemable', a word more fitting and actually used for a [[WesternAnimation/PussInBootsTheLastWish future]] [[Characters/PussInBootsJackHorner animated character]] Creator/JohnMulaney voiced.

** Seasons 6 and 7 are both considered to be BrokenBase at best. Some people like them better than 4 & 5 but aren't as well liked as the early seasons, especially in regards to the [[WesternAnimation/HumanResources2022 short-lived spin-off]], which takes place between both of these seasons.

* SeasonalRot: Tends to be a tie between Seasons 4 and 5; the former was criticized for a perceived overreliance on shock value while the latter featured most of the characters being {{flanderized}} and holding the JerkassBall.

* InformedWrongness: In Season 2, Episode 9 "Smooch or Share", after Andrew admits to having masturbated to Nick's older sister Leah, Tyler has a very valid point when he tells Nick that they don't want to think of their big sister in such a way and for masturbating in his house. And so Nick is understandably pissed off and disgusted by this, but Andrew, with the help of Maurice repeatedly defend themselves and attempt to justify what they did. But this is despite the fact that Andrew crossed a line by masturbating to his best friend's sister (who witnessed it no less) and in their pool house on top of it all, and when he reveals that he's masturbated in Nick's house plenty of times before, including when Nick is sleeping, Nick is once more rightfully upset by this new knowledge. However, while Andrew does own up and feel bad for what he did, the episode treats it as if Nick was wrong to get mad at Andrew for this as Nick himself even says that he was "mean" to his best friend and blames Tyler for encouraging him to call out Andrew for his indiscretions. Granted while Andrew does have urges that he can't exactly control due to puberty and Maurice's influence, Nick can't really be faulted for being rightfully upset upon finding out about how his best friend has constantly done such things in his house and to his sister.

** The Season 5 finale has Jessi realize how callous she's been to Missy and apologize for taking over her affinity group. However, Missy's own behavior in the season, particularly spreading vicious SlutShaming rumors about Jessi and Ali that culminate in a massive physical fight, make it harder to see Missy as a victim of Jessi's behavior as opposed to them ''both'' being petty and impulsive. The season does depict Missy's hate-filled behavior as unsympathetic, but the final episode implies most of the blame is on Jessi in the situation, despite Missy acting more maliciously as opposed to just InnocentlyInsensitive.

** Caleb, in all his ambiguous disorder glory. He's more or less a background character, but he's so [[InnocentlyInsensitive innocently blunt]] and [[CaptainObvious obvious]] when he appears, that fans love him.

* DontShootTheMessage: While the show might be crass to many people it raises several valid and important points and has many solid aesops regarding themes such as body-positivity, consent, growing up, etc. To say nothing of the Planned Parenthood episode, which was instantly controversial.

* AwardSnub: In 2018, Mark Rivers was nominated for an Emmy Outstanding Music and Lyrics for "Totally Gay", but lost to "Come Back, Barack" from ''Series/SaturdayNightLive''. A year later, the show itself was nominated for Outstanding Animated Program for "The Planned Parenthood Show" but lost to ''WesternAnimation/TheSimpsons''.

* AudienceAlienatingPremise: The series is about a group of teens going through puberty and first exploring their sexuality, portraying the issue with such extreme, in-your-face frankness, many people claimed it was bordering child pornography. The creators were aware of it, as the art style used is deliberately ugly, probably chosen to dissuade ephebophiles. Critics who saw it actually liked it, but other people may be appalled by either the subject or the art style, and it's not very likely that the show gets watched by actual teens going through puberty since they would feel the series is too close to home.

** Many viewers, especially those who haven't seen the spinoff ''Human Resources'', assume Montel is a male character, likely due to their resemblance to Maury, but they're really nonbinary. While they do get a song about how their gender identity isn't determined at birth, it's easy to assume they end up growing into a male due to their facial hair. However, ''Human Resources'' consistently uses gender-neutral language for Montel even as they age, making it clear this is their identity.

* ViewerGenderConfusion: Tito the Anxiety Mosquito is referred to with "she" pronouns, despite her masculine-sounding name convincing viewers she's a male. She does have a female voice, but one would expect a mosquito's voice to be high-pitched either way.

* BizarroEpisode: "Pillow Talk" involves [[spoiler: Jay's brother]] impregnating his [[SuddenlySpeaking now-sentient]] pillow and the two of them spending the rest of the day going through the stereotypical motions of a real life pregnancy (morning sickness, feeling the baby, the baby [[spoiler:turning out to be Jay's brother's]], etc), the drama of 13-year-old Jay now being the father of a 40-year-old pillow's baby and eventually [[ExpressDelivery the pillow giving birth]]. It ends with the pillow leaving him and taking their half-pillow, half-human hybrid baby with her and Jay deciding having sex with his bathmat instead. ItMakesJustAsMuchSenseInContext.

** At the end of the third season where Nick and Andrew officially end their friendship, fans are divided on whether it's Nick or Andrew who's more at fault for the deterioration of of their friendship. The fact that this conflict continues into season four (for the first four episodes) just makes it worse.

*** While Jay and Matthew still have a way to go, they are capable of change (despite what their classmates think), and they both become better and happier people. Matthew becomes nicer and gets a boyfriend, and Jay, after getting a loving family for a while, gives it up for his friend Nick when he sells his medication, mainly because he believes his ADHD medicine would help everyone with a stressful test (it doesn’t). He becomes accepted by his family in the season finale, which is something he’s always wanted. Luckily though Coach Steve is also (almost) always around (and Nick’s parents are only a phone call away) so Jay still (kind of) gets the parental care he needs. In the next season he also gets a girlfriend in Lola (but it didn't last).

** Val and Leah's surprisingly healthy relationship indicated that Val could develop into a nicer person, possibly changing some dynamics in the Bilzerian family and developing Val distinctly from Kurt. However, the relationship appears to end offscreen and Val goes right back to his typical BigBrotherBully self by Season 7.

** When Sharon curses about Greg's new girlfriend, is it because she's jealous that her deadbeat ex husband has a girlfriend when she just got dumped and is generally succeeding in getting his life together while she's struggling, or does she just hate him so much at this point that she doesn't ''want'' to see him succeed? A combination of the two, maybe? Similarly, does she think that moving Jessi away by force is for her own good, is it a way to prevent Jessi from gravitating more to her father or is she more concerned with doing things that'll help her own psyche that she doesn't even bother to care about her own daughter's any more? Likely a good combination of the latter two (poor Jessi).

* ArcFatigue: Andrew and Nick both often get plots where they seem to be hitting it off with a girl, only for their immaturity to ruin it. This is a major factor in why the characters have become so polarizing in later seasons, as they don't seem to return the lessons they learn from these experiences and it becomes more and more cringeworthy over time. Andrew in particular has had several seasons of self-proclaimed improvement, but seems to regress back to being gross withim episodes for the sake of CringeComedy.

* BrokenBase: Unsurprisingly, given the subject matter at hand.
** Similarly, there's the purposefully exaggerated art style. For some, it does work in its own way, much like the writing, and has its appeal. For others, it's just ugly regardless of IntendedAudienceReaction.
