Definitely a contender within the Rick & Morty, Family Guy, Aqua Teen Hunger Force, Adventure Time, BoJack Horseman, South Park realm of edgy adult animation. Works best when going for subtlety over the big laughs.
First couple of episodes were incredibly good, but it kinda loses something between useless musical segments and the overtly exaggerated cheekiness of certain situations. Moreover they could have paid some artist to sketch better characters who could have distinguished the show from the usual family guy crappy design.
That kind of show that makes you want to grow up watching it, to be honest. Easy to watch, relatable in some ways and so appealing... The idea of the hormone monster is brilliant - a human friendly representation of our thoughts pushed by our teenage desires and impulses. And then the generic has that Charles Bradley powerful theme, 'Changes' - it created such a revamped idea of that song.
Not quite as pure shock value as it may seem at first, but still very shallow. Big Mouth has some of the ugliest animation, cheapest gags, and laziest voice acting I have seen in a while. This is a major miss from Kroll and Mulaney, who are normally very witty. It has a bit of intelligence in spots.
Season 1, I can't really remember. Season 2 is a hilarious step up though, with every character forming a larger identity (which mirrors its subject matter perfectly). Although it's not as groundbreaking in style, structure and writing than its Netflix co-toon Bojack Horseman, it's still a laugh for anyone that's been through puberty with similar experiences. What are you gonna do?
