Filmmakers Judd Apatow, Seth Rogen and Evan Goldberg make lowbrow comedies for highbrow audiences. With films like "The 40-Year Old Virgin," "Knocked Up," and their current gem, "Superbad" (directed by Greg Mottola), they have begun, in their own quiet way, to re-write the rules of the modern sex comedy, making films that, despite their R-rated blueness, are just a tad more insightful, a little more nuanced, and a trifle more literate than most films in that genre.

The characters in their movies may seem at first blush to be mere photocopies of the nerds and losers familiar to us from all those post-"Animal House," pandering-to-youth comedy hits of the late 1970's and 1980's. Yet, there is something rather different about these individuals, a difference that it is not always all that easy to put one's finger on. They seem somehow more reflective and self-aware than their earlier counterparts, more able to step out of their skins and see themselves for who and what they are. It's almost as if these characters have had the added advantage of seeing themselves reflected in all those earlier movies (one imagines they've spent a great deal of their childhood reveling in "Revenge of the Nerds") and of extracting important lessons from those films to help them chart their course through life.

The storyline, in and of itself, is hardly original. The screenplay by Rogen and Goldberg chronicles the misadventures of three teenage super geeks determined to go to any lengths or suffer any humiliation to be part of the "in" crowd at school. With only a few days left before graduation, Seth, Evan, and super-nerd Fogell - an outcast even the outcasts can feel comfortable ostracizing - decide that the time has come to take some drastic action if they hope to have any chance of losing their virginity before high school ends. Thus, Seth cooks up a scheme to smuggle booze into a graduation party being thrown by one of the hottest girls on campus. It is the expected setbacks they encounter as they go about the business of achieving "coolness" that provide the comic energy for the tale.

As they did in "Knocked Up," the writers capture the way people in the real world actually speak. The dialogue may be crude and vulgar, but it is also sharply observant and wickedly funny as the characters lament the unfairness of life and reveal deep-seated concerns and feelings about themselves and each other. What's nice is that the characters in this film not only sound like people we might encounter in everyday life but LOOK like them as well. Even the "beautiful" people in this film aren't drop-dead gorgeous, just believably well put-together and attractive.

Jonah Hill, Michael Cera and Christopher Mintz-Plasse are so authentic and convincing in the roles of Seth, Eric and Fogell, respectively, that they have us securely in their corner from the very first moment they appear on screen. Rogen and Bill Hader ("SNL") also have a good time playing goofy cops, although their characters aren't as finely drawn or interesting as the three main characters, and the scenes with them do tend to drag a bit.

It is crucial to point out that, amidst all the blush-inducing, foul-mouthed hilarity, there's an incredible underlying sweetness to "Superbad," particularly in the final two scenes of the movie.

Together, this team of talented filmmakers is making it fun to go to the movies again.
