Many years after “National Lampoon’s Animal House” first came out, a friend of mine re-watched it and said it seemed “slower” than he remembered it. Unlike the gag-on-gag-til-you-gag comedies of more recent generations, this film has a plot, and plot exposition, and relationshippy subplots, and there are several physical comedy scenes featuring John Belushi with almost no dialogue. And the shocking-for-1978 nudity and language is common now. That doesn’t mean it hasn’t aged well. Despite some non-PC asides, the big punchlines are still brilliant examples of comedic craftsmanship. Worthless and weak? This film changed comedy and, in some ways, college.
