Reviewers say 'Big Mouth' tackles puberty, sexuality, and coming-of-age with humor and honesty. The show addresses serious issues like consent, body positivity, and mental health through relatable characters and surreal elements. It is praised for its clever writing, memorable characters, and catchy songs. However, some reviewers find the show's raunchy humor and animation style off-putting. Overall, 'Big Mouth' is seen as a bold, insightful, and entertaining take on adolescence, though it may not appeal to everyone due to its mature content and unconventional style.
