I liked the science - it all makes sense with current views on black holes and time dilation - all good with me up to the last 15 min.
However, I still don't get it that on the water planet, which was so close to the black hole that hours passed in years on earth, the gravity effect of the black hole caused massive tsunamis but the observable gravity was not high and it did not seem to overly effect the movements of humans. Surely objects with mass on a planet so close to the gravity field of a black hole would be seriously effected depending on the clashing gravity fields and rotation of the black hole and the adjacent planet?

I really liked the robots. Nicely done.
Caine - meh - whatever, not so bad.
Damon - strange - maybe just not used to seeing him as a real arsehole.
Hathaway - Damn! But wasted in the spacesuit for almost the whole movie!

2001 is still the only realistic sci-fi space movie.
Gravity was good, but can't really be classed as sci-fi.

Cheers,
John K

Gravity is the weakest force of the four fundamental forces. It is so weak that compared to the strong force, the nuclear binding force, it is only 10 > -40 as strong. My guess is as long as you have NOT reached the horizon of the black hole, gravity is not very noticeable. Even if the black hole is very massive. While the Earth's moon affects tides, we do not notice the Moon's gravity since it's small compared to Earth's gravity. At the center of all galaxies is a supermassive black hole, e.g., billion solar masses. If the gravity of the supermassive black hole was extremely strong at a distance from the center it would suck all of the galaxy into the black hole and the galaxy would not exist, no? But the galaxy is more or less in equilibrium. At the horizon of the supermassive black hole there is some sucking in of nearby material and that's what produces the intense white light visible at the center of the galaxy and what produces the extremely large black hole over time.
