I can see this becoming a new standard: films like "My Dinner with Andre" may not "benefit" in the gimmicky things-flying-at-you way, but every film in 3D does benefit from the immersive element of the third dimension being there. It's like what Lucas says--it doesn't have to be about things poking you in the face and reminding you its 3D, after a few minutes it becomes an invisible process of deeper immersion into the visual presentation of the film. This could become the next step after the introduction of color photography, or it could not--but if it did, it wouldn't be inherantly bad and unnecessary, any more than color is. Does every film need to be in color? Do most films use color in a consciously noticeable way? Not really. But color is more natural, because we see the world in color. So the same is with 3D; we percieve reality in three dimensions. Who knows, 2D photography could in the future be seen as self-consciously stylistic, like how black and white photography in movies is today.
