The question is, where has he gone? These words don't come easy, but Martin Scorsese, at this current juncture in cinematic history, has disappeared. Once a maestro film-maker who advocated anarchy of the soul - see De Niro's Johnny Boy in Mean Streets or Joe Pesci in GoodFellas - Scorsese delighted in holding up a mirror to America's underbelly, and he did so with that most subversive of narrative tools: humour.
As for Spielberg's intentions to once again adapt a lost Kubrick masterpiece, the uninitiated may smirk, but there is still no questioning his skill as a director. In fact, while Spielberg could have benefited from his colleague's artistic prudence, his powers as a producer and his ability to get projects made are second to none.
I'm very fond of conspiracy theories - they're intriguing and fun, in their twisted way. But they're also very frustrating, because any big reveal will always be just out of reach, always just around the next corner. You want them to be true, and maybe some day they will be, but they're never true now.
