It’s the last day of school, and best friends Molly (Beanie Feldstein) and Amy (Kaitlyn Dever) are ready to bid high school goodbye. They’ve been serious students, buttoned down and focused, and their hard work has paid off: they’re off to Yale and Columbia respectively. But their pride is tamped down a little when they learn that that many of their classmates are also headed for the Ivies – this despite the fact that they rarely seemed studious, and made lots of time for parties and fun. “I’m incredible at hand-jobs but I also got a 1560 on the SATs,” says one.

Molly is particularly devastated; sure she’s the valedictorian, but did she sacrifice fun for nothing? She doesn’t want to show up at college in the fall a party virgin. Her whole worldview is sliding down a crap chute, and her instinct is to dive in after it. Luckily, they have one last night before graduation, and Amy’s departure for a summer of volunteering in Botswana. One night to make up for 4 years of skipping parties and feeling left out of the in-crowd. They set their sights on Nick’s party – the most effortlessly popular kid in school (played by Mason Gooding, son of Cuba Gooding Jr).

The ladies do not get from point A to point B without boatloads (and sometimes they are literal boatloads) of shenanigans. This is Superbad, only because it’s girls, it’s much smarter. And it seems like this one night of trying to party teaches them more about themselves than the previous four years of high school. That sounds about right, doesn’t it?

The movie gets so much right even as we learn how much the girls have gotten wrong. Molly always assumed she was purposely excluded, but it turns out these kids are all too happy to greet her socially; her exile was self-imposed. How maddening, isn’t it, to discover that too late – and a good reminder for us all to check in with ourselves. How often do we impose our own limitations? Amy tackles her fears while Molly checks her ego, and her assumptions. The two women in the lead have amazing chemistry and it’s a lot of fun to witness the particular dynamic of their friendship. You and I know that college will test the bonds of their friendship, and inevitably change it if not crush it outright. They’re starting to have inklings that this might be so. So this last night out has some tangible pressure to it. Beanie Feldstein is a cinematic lantern, lighting up every screen she’s on, and lighting the way for others. Kaitlyn Dever is an excelling pairing for her, able to play off her energy in a more conservative and subdued way, while still holding her own.

Olivia Wilde tries out the director’s chair and seems to find it a pretty comfortable fit. She’s got an eye for letting actors do their thing; so much of the best bits feel spontaneous and are the best kind of weird. She’s also got an amazing feel for music – she introduces characters and themes with pop songs, and it really took me back. I bet most of us can come up with a soundtrack of our own high school experience. Music is such an important part of that time in our lives. I still surround myself by music constantly, but I will never again spend the day on my bedroom floor inhaling lyric booklets, or spend hours recording stuff off MTV like I did then. I know which songs I kissed to, slow-danced to, had sex to. Which ones we played on repeat as we drove recklessly and restlessly around parking lots doing donuts, which ones played at the diner as we split an order of fries, which ones we cried to when boys were mean to us, which ones accompanies us down the aisle at our own graduations and commencements. Wilde seems to have an intuitive sense of that, and I caught it.

There’s a theme in Booksmart that is hinted at but never spoken of: class. As in economic and social class. Molly points out the school’s 1% (Billie Lourd and Skyler Gisondo, whom Sean finds uproariously funny), but it’s clear that the Los Angeles high school as affluent as heck. Everyone, it seems, except for Molly. Not a single thing is ever said about it, but we see that she lives in an apartment building while everyone else has a McMansion, and her parents are absent from the film. So when Molly discovers that all her other classmates also got into good schools, she berates herself for having skipped the fun when she didn’t have to. But you and I know that she probably did: that kids like Molly have to earn their way in, but kids from rich families do not. They have legacy status, they know alumni who can pull strings. Their families donate money to schools. And, as we’ve seen in the news recently, they pay money to fake their way in on a little-used athletic scholarship or some other fraudulent means. College admissions are not the meritocracy we want to believe they are. There are very valid reasons why Molly worked so hard and others did not, even if the film never states them. So maybe Molly’s takeaway was to loosen up a bit, and experience life, which are not bad lessons. But for us, it’s a little bit more than that.

Even with these subtle layers, Booksmart never stops being fun. The cast is lively and diverse, the tropes are thankfully on the unexpected side, and the movie has a great pace. Plus it has an exception friendship at its centre. Just when you think we’ve said all there is to say about high school, Boomsmart is a charming, genuine and clever addition to the field.
