Saw it :thumbup:
First, it's a really good movie, and solid sci-fi. Everything depends on the usage of technology and logic. Characters are OK, and the psychological part is well portrayed.
9/10, just because 2001 deserves 10/10 (larger scope and a greater challenge for the state of the art at the time).
The classic sci-fi themes are all in Gravity: confrontation with the unknown, pushing to the limit - both physical and technical-, the meaning of life, why explore, etc, etc.
Visually it's completely realistic (for a movie). They got the computer interfaces right (at least for me).
And you get to see through the Vizor. That has blown me away as far as realism goes. She controls the Soyuz using the Vizor and the lateral viewports, just as we know it should be.
The russian part of ISS is also well recreated. Basicly, the only changes to real hardware are justified by the story and artistic license.
Any Orbiter fan MUST see this, and disregard any "it's scientifically wrong" comments. It's not a documentary, it's not a physics lesson.
It's as real as James Bond, and that is considered as spy / action movie, not phantasy.
If all the misconceptions about space (mostly wrong) could be reduced to what's shown in "Gravity" (mostly correct) I'd be very happy.
