No surprise, DeVito's self centered abrasiveness meets with antipathy. Army officers don't care. Convinced of their own worthlessness, DeVito's students are disinterested, at best. During the semester, DeVito, mellows, students learn enough to advance,and Army brass begins to appreciates the new teacher.
The best part of this film is not DeVito's or the student's redemption but the film's beguiling Shakespeare presentation. DeVito teaches the Bard with passion. The writers deliver illuminating, focused student dialog. As one who didn't "get" Shakespeare until seeing MacBeth a year after graduation. This movie was a better class than anything I took in high school or college.
Enjoy the film and the class.
