'Superbad (2007)' is crude, coarse and quite immature but it's also undeniably and undoubtedly hilarious, providing plenty of laughs and thus succeeding in it's primary function - which is more than can be said for most so-called 'comedies' nowadays. Sure, it's low-brow and vulgar but no-one ever said that rude humour can't be amusing too and that's exactly what this is from beginning to end: an entertaining romp that races through its relatively thin plot without ever taking itself too seriously or compromising its story for the sake of extended improvisational routines. It actually comes to a close with somewhat of a moral lesson. It's truly funny, and sadly that's an adjective I rarely get to use any more. 8/10
