Oblivion begins with a two-man crew making final preparations and repairs to equipment on Earth before rendevous with a final emigration to the moon Titan after a war causes the ruin of Earth.
Tom Cruise really makes the movie, as everything depends on the character of Jack Harper and, more than his actions through the movie, his reactions as a person and human being. Throughout the movie, we see Jack’s attachment to the planet of his birth, and his reticence about leaving it. Indeed, despite orders to leave and regroup with the others enroute to Titan, he longs to stay.
This humanity he displays, along with his attachment to our planet is put into stark display later, as the plot unravels. As we come to grips with Jack’s revelations, the question naturally occurs, what makes us human? And what makes us unique?
