By Zak JasonOf all the on-campus events students neglect, the Baldwin Awards screening may be the most unfortunate case. Nowhere else on campus can you get three free hours of on-screen sex, drugs, and collegiate melancholy. You could flick on your cheap dorm television and watch Good Luck Chuck again on the Boston College movie channel. But in the future, you could enjoy the free popcorn and watch the work of your fellow students on the mammoth screen of Devlin 008. On Thursday night, the film studies program and Boston College Magazine presented the 26 films of the fourth annual Baldwin Awards, a refreshing array of documentaries, comedies, experimental shorts, musicals, and dramas. A few dragged to redundancy and a few milked college humor cliches dry, but the vast majority of the submissions entertained, and a few even inspired.
