You can put your hero arbitrarily in tears to show he has depth; that gets done here. You can show him having revelations — college kids want to know who’s single; we should put a “relationship status” entry on Facebook! — and there’s some of that, too. For shorthand, you can make your intelligent hero schlubby, Jewish and unathletic. That historically reads as intelligence to movie audiences. You can also make him awkward with girls.
