On those rare occasions when a great motion picture reaches multiplexes, the film critic must add another aspect to his or her job description: that of cheerleader. It is incumbent upon those of us who routinely dissect movies to applaud the arrival of something like Minority Report. Writing a review isn't enough - we have to get out there and actively stump for the movie. The underlying reason is sound: if Minority Report makes a lot of money, the studios will be encouraged to fashion more films of this sort. And that is a good thing - not just for science fiction lovers but for fans of intelligent, thought-provoking pictures of all genres.
