Synopsis Major Roy McBride (Brad Pitt) has been called for a special mission by SPACECOM, a capitalist space agency to investigate a cosmic electrical anomaly that might have been coming from the Lima Project in Neptune, which also where his father, H. Clifford McBride (Tommy Lee Jones) was involved. But all contact was lost for 16 years. Roy take this as an opportunity to reconnect with his father.
The absence of humanity Despite breathing in space, it does not equate to being alive. The soundless void. The absence of the smell of air. The aroma of home made cooking. The simple face to face chat with family and friends.

A void as vast as an empty human heart
So is the heartbeat of Roy who never went high in any mission crisis but went up the moment he lost his father. The feeling of lost of someone he loves and adore. Someone that he missed for more than 16 years. His father Clifford has become as void to any feeling or humanity. As void as the outer space. The space has consumed him.
Akin to what Captain Willard goes through in the Apocalypse Now where he went through the Nung River to seek for Colonel Walter E. Kurtz which has been consumed by the war.

The horror...
Exploration and colonization of outer space by mankind is akin to spreading cancer out to the cosmos. We as a species has damaged the heaven called Earth. On the moon, greed still rules. Roy’s convoy being attacked by pirates. The attack of the baboon is a metaphor that human is still an ape no matter how far they explore.
The further we go out into the vastness of the void, the more we realized that there is going to be no other place like our home planet Earth, and it is truly a heaven.
It is ironic we seek intelligent life elsewhere when we neglect the ones that is right before us. Isn't it ironic that we seek to bring life to a dead planet when we are taking the life out of the planet we are living in? Can we be considered as an intelligent life by doing so?

Earth is the heaven that we are looking for

Even Agent Smith having problem classifying our species.
I enjoyed Interstellar more than this one though
