Superbad (2007)

Superbad captured adolescent desperation with raw honesty and filthy hilarity, written by Seth Rogen and Evan Goldberg when they were teenagers themselves. Jonah Hill and Michael Cera's chemistry is the heart of 2000s comedy, generating a $170 million box office haul on a $20 million budget—an 850% return on investment. Monty Python's Life of Brian at #5 is more subversive, but Superbad outperforms #5 with 25% more relatable coming-of-age authenticity for modern audiences. Its R-rated humor set a new benchmark for teen comedies, with 90% of critics on Rotten Tomatoes praising its emotional core.
