Just watched this on Blu Ray, and the sound levels were awful. Thsi is what I got from the film:
mumble mumble dust mumble whisper mumble earth is dying mumble mumble mumble fly to a wormhole mumble mumble astronauts explain basic physics to one another mumble mumble no one takes readings of planets before landing on them, resulting in huge waste of life, equipment, time, and money mumble mumble HANS ZIMMER'S PIPE ORGAN mumble mumble Gravity is important - except when you're near a Black Hole - then you ignore it mumble mumble HANS ZIMMER'S PIPE ORGAN AGAIN
The film had gripping moments - but the script was self-indulgent and made no sense so much of the time. For example - why did the crew never take readings of the conditions of the planets they wanted to visit, before landing on them? Because they didn't it resulted in a huge waste or life, equipment, time, and money.
It was also Hollywood casual discrimination by the numbers: white man is boss, black friend dies, and female lead is hysterically emotional and exists to make babies (literally).
The film was too long as well. The Damon scenes added nothing but a huge digression - in fact, they could have dropped the whole planetary system bit and simply had the Black Hole experience within the wormhole itself. It would have made just about as much sense, but drastically cut the film - and a ton of silliness.
The ending? White man gets into ship, flies away into the ... sunset? What happened to earth? Looks like they didn't do well saving it to have mined so much material as to create the Saturn space station.
The film had potential, but IMO was badly put together.
