BUBBLE BOY. Finally saw The Aviator. It's sort of Citizen Kane with the greatness left out.

Our troubled, Promethean hero in this case is Howard Hughes, with a mania for perfection instead of a mania for acquisition, and a manic-compulsive disorder instead of Rosebud. His wound and his bow, so to speak, are a matched pair, and the movie does a pretty good job of showing us that, aided by a very good performance by DiCaprio, who makes clear that Hughes' demented impulses proceed from the same well as his creative ones.

The images in The Aviator are dazzling, and there are some passages in which the story really breathes -- as when Hughes takes that other magnificent monster, Kate Hepburn, up in his flying machine, and for a few minutes seems to really believe that he might have something in common with another human being.

But that inevitably collapses for Howard, and soon we are just watching him grow more monstrous and more magnificent by turns. It seems clinical, less like a story than a case study.

There are some reasons I can identify. For one thing, there is a prologue in which we learn how Hughes got all fucked up: black soap, coloreds, quarantine. It lasts a few minutes. I think Scorsese's instinct was that audiences would need an explanation, but a long, belabored explanation would have been superfluous. He's right in a way: Welles himself dismissed Rosebud as "dollar-book Freud." But Welles chose to make a mystery out of Rosebud anyway and left it for the end to reveal.

Maybe mystery has its own meaning in Kane: the thing you keep looking for that will sort everything out, an obsession that the audience and the hero can share. In the end, Rosebud is revealed to be a cheat. But (in my experience and probably yours) the viewer does not feel cheated, because we know by then that we have at least seen Kane in a way that he could not; Kane himself has suffered the cheat. His sled, along with his acres of other possessions, rises into black smoke like Cain's (!) refused sacrifice.

He was some kind of man. What does it matter what you say about people? We can follow Welles' obsessions throughout his career. For years Scorsese seemed to be on a course like that. His characters were all blindly struggling toward transcendence without knowing how, grabbing whatever was at hand, acting against their own evident interests because something they couldn't name was out there that they had to have. His greatest hero was Jake LaMotta, a man incoherent on every level -- verbal, emotional, spiritual -- who knew nothing but fighting, couldn't learn anything else, and wore himself down against the world.

Hughes follows that template, but to less avail. He's no less helpless than LaMotta, and Scorsese's craft is, if anything, improved. What's missing? Maybe the stakes -- not Hughes' or LaMotta's, but Scorsese's. In GoodFellas you can see it happening: brilliant as it is, you can tell that these monsters are not transcendent, but merely monstrous. That's the point, and that's why for all its gore it's so funny. But by Casino I found myself wondering something I'd never wondered with Scorsese before: Why did he make this? And why am I watching it? The final shot of DeNiro's exhausted countenance seemed like the end of more than a movie. It gave me the same feeling some of the late Sopranos episodes have given me: that the author was as sick of these people as I was.

In the years since then, Scorsese has been very active. He's a player in Hollywood, and can get big pictures made. His technique just gets better, and his energy remains high. Still, I remember when one of my favorite things about New York was that I got to see every new Scorsese movie opening day. That I no longer feel that way may have much more to do with me than with him, but I felt that way about Kubrick till the day he died. It had less to do with technical brilliance than with my faith that he still had mysteries to reveal. Nobody much likes Eyes Wide Shut, but it lingers in my memory: the boundless interiors and the claustrophobic exteriors; the half-comical, half-pathetic Tom Cruise (cannily used, like Ryan O'Neal in Barry Lyndon, for his weaknesses as much as his strengths) assuring everyone, "It's all right, I'm a doctor"; the scene at the pool table in which Sydney Pollack blandly tells -- invents? -- what has really been happening all along. A man who thinks he has lost something important, and finds that he has no idea what it means to really lose; a movie more about class than sex. It means more to me than The Aviator already.
