sentences:  Thomas Patrick Doherty writes that "the adult villains in teenpics such as ... "Ferris Bueller's Day Off" (1986) are overdrawn caricatures, no real threat; they're played for laughs".Yet Silverblatt also remarks that casting "the principal as a comic figure questions the competence of adults to provide young people with effective direction—indeed, the value of adulthood itself".Adults are not the stars or main characters of the film, and Roz Kaveney notes that what ""Ferris Bueller" brings to the teen genre, ultimately, is a sense of how it is possible to be cool and popular without being rich or a sports hero.
