The usual themes, childhood isolation and the collapse of the nuclear family, explored through the relationship between human and extraterrestrial. Spielberg uses this idea to craft a moving, intimate, often claustrophobic film (about the clash between 'belief' and cynicism) that is also genuinely surreal; the apocalyptic imagery contrasting against the suburban American setting to create a sense of real danger.
Like most of Spielberg’s work, ET restores a sense of childhood wonder. This mode becomes both text and subtext, and informs the film’s visual style and sentimental machinations. ET doesn't undercut this systematic naivety with the cynicism of adulthood, but respects the emotional experience of childhood, its joys, fears, and its own unique wisdom. http://filmcapsule.com/2014/06/30/e-t-the-extra-terrestrial-1982/
"Back to the river! Back to the forest!" Sublime hokum from the golden age of science fiction, otherwise known as my own childhood (maybe yours, too), E.T. overwhelms the wonder receptors in the brain, turning susceptible viewers into weeping, grinning, dopey miracles of the human spirit. Want a Coke? Don't ruin it.
