Cameron shoots out like a meteor. Suddenly, he has crafted not just a good film but a genuine work of art. There is not a single wasted frame in the picture. I've read the screenplay a couple of times. Several changes were made for the film's final cut. Most of them strengthened that cut and indicate the workings of a mind that realized something special was happening. Something different from his other films. Something that demanded him to summon (and reveal) all his talent.
