Superbad is exceptionally funny. In terms of how often you lose your breath from laughing, it’s hard to think of a better movie than Superbad. Watching Superbad probably burns between 118 and 315 calories. This unrated version anyway. The rated version would burn about four minutes less. Next time I watch it I’ll have to try to measure it on my Apple Watch. It’s one of the funnier films ever made. A smartly done, utterly obscene teen male virgin comedy. It’s a peerless success in terms of those laughs, a combination of script, actors, and material. Utterly obscene teen male virgin comedies—the kind screenwriters Seth Rogan and Evan Goldberg apparently grew up watching—needed the Internet and culture to hit 2007 to fully realize the genre’s potentials.

But it’s just a smartly done, utterly obscene teen male virgin comedy. The script’s got an amazing first act, plotting-wise; the rest of the movie doesn’t. Director Mottola takes a hands-off approach, not really showing much personality until the last shot when you get the feeling he wishes he were making a different, less utterly obscene teen male virgin comedy, but maybe even smarter. Lead Jonah Hill (playing “Seth”) loses his first act protagonist role once the second act hits. By the third act he’s even more reduced. Instead, it’s more about Hill’s best friend, Michael Cera (playing “Evan”), and their awkward third wheel, the hilarious Christopher Mintz-Plasse. They’re all high school seniors. It’s the last two weeks of school. They’re going to a party.

Mintz-Plasse’s side plot is all about his fake ID, liquor, and two party animal cops (Bill Hader and Rogen—who are playing older analogues to the teen boys, but not generally, it’s not one-to-one). It’s the even funnier stuff in the extremely funny movie. Because even though Hill and Cera have a lot of humor in their own liquor hunt (Hill promised dream girl Emma Stone he’d bring all the booze for her party, Cera promised dream girl Martha MacIsaac he’d bring her a special bottle of vodka), they’ve also got their “best friends since the fourth grade who go to different colleges and can’t be joined at the hip anymore” arc. For all their excellent insights into the male psyche, Rogen and Goldberg can’t crack that arc. Meanwhile Mottola is focused on the “boys finally learn girls are people they want to spend time with” arc, which is really awkward because Hill, Cera, and Mintz-Plasse are way too old for that arc.

Their being too old for it does provide a decent backdrop for some of the jokes, but the only time it gets directly referenced is with dream girl Stone. She’s too wise for Hill; he’s been intentionally confusing maturity and vulgarity his whole life and it won’t work with Stone. Meanwhile Cera gets this strangely paternalist arc with MacIsaac, which—given how shallow Cera’s performance schtick gets as the film goes along—is really bad for her. MacIsaac gets a little more screen time than Stone (it feels like a lot more; Stone’s forgettable) and somehow even less character. They’re both dream girl caricatures (albeit 2007 ones). The film never even hints at them being anything more. MacIsaac’s got friends, Stone’s got parents out of town. Done.

Other big problems include the progressive gay jokes. It’s lazy writing more than anything else. Superbad’s got a really big anti-toxic masculinity statement it hints around making without ever having the balls to make it. Also interesting is the lack of teen male virgin shaming, which sort of breaks the genre.

I also don’t understand how the Richard Pryor shirt Hill wears through the first act didn’t become the Garfield-in-the-car-window of the late aughts. Pryor’s expression gets laughs of its own, like he’s offering commentary on the surrounding events. It’s awesome.

Lots of Superbad is awesome. It’s peerlessly funny. It’s also astoundingly not ambitious.
