“Star Wars” is like getting a box of Cracker Jack which is all prizes. This is the writer-director George Lucas’s own film, subject to no business interference, yet it’s a film that’s totally uninterested in anything that doesn’t connect with the mass audience. There’s no breather in the picture, no lyricism; the only attempt at beauty is in the double sunset. It’s enjoyable on its own terms, but it’s exhausting, too: like taking a pack of kids to the circus. An hour into it, children say that they’re ready to see it again; that’s because it’s an assemblage of spare parts—it has no emotional grip. “Star Wars” may be the only movie in which the first time around the surprises are reassuring…. It’s an epic without a dream. But it’s probably the absence of wonder that accounts for the film’s special, huge success. The excitement of those who call it the film of the year goes way past nostalgia to the feeling that now is the time to return to childhood.
