Movie critics can make or break a new release’s potential success. And while picking the duds is easy, what requires more skill is identifying when you’re watching what will eventually become a classic. In fact, even the most famous film critics can have a hard time recognizing greatness. Take Stanley Kauffmann of The New Republic, for example. In his review of Stanley Kubrick’s2001: A Space Odyssey, he described the film as “so dull, it even dulls our interest in the technical ingenuity for the sake of which Kubrick has allowed it to become dull.” Or how about Joseph McBride, a Variety critic who thought he hit the nail on the head when he dismissedMartin Scorsese’sGoodfellas, one of the best gangster movies ever made, as “dramatically unsatisfying.” Here are 33 more hilariously bad reviews of what would become beloved, timeless cinematic classics.
