The premise of the movie is the protagonist's father went on a mission trying to find extraterrestrial life...life beyond what we know. Something happened on the craft that caused problems back on earth. So the protagonist is sent to fix the problem. When he arrived he found his father had basically gone insane. 30+ years of solitude will do that. He killed his crew in his insanity because they wanted to go back home...the crew had come to terms of the reality of the situation...that nothing was out there. The protagonist’s father was dead set though on validating his life’s pursuit...he didn’t want to accept the reality...the facts...the truth. So when the protagonist’s father saw his son again I think he subliminally finally realized he spent his entire life searching for something that was never there. He left what was tangible and real behind....his family. And he just couldn’t come to terms with this and essentially committed suicide; his son tried to stop him but he told him to let him go. The son finally let go and let his father drift off into space.
It’s sad when you think about it. You can spend a lifetime searching for something that isn’t there and lose sight of what is right in front of you. His father found tons of data on all these vast and beautiful worlds....but there was no life on any of them.
The only thing that disappointed me is when Roy returned home there wasn’t a better ending to kind of wrap it all up. The movie is so deep most people won’t see the point. That is why I think a good ending would help everyone understand the underlying meaning of the film so it doesn’t get bad ratings from people who think it’s just rambling on with no point. It’s a film that requires you to think and interpret the underlying point of the film.
All in all a great film, great visuals, great acting. The main point to take home from the film is this...don’t waste your entire life searching for something that is right in front of you. Cherish the life you have been given and love your family and fellow humans.
