Technically this film is stunning. Lots of good portrayals of microgravity with very few gaffes, some of which were clearly thrown in for nice visual effects (like a helmet staying stationary in the center of a rotating and accelerating landing module).

Orbital mechanics are also totally bungled beyond repair: 1) You won't see debris that hits you at hyper-sonic speed - it's too fast to track with your eyes. 2) There's no way to generate such a dense debris fields even if you destroy all the satellites. Besides, it'll take days for fragments from a satellite explosion to collide with other satellites. 3) And of course, flying from Hubble telescope to the ISS using jetpack is impossible - they have wildly different orbit inclinations and heights. 4) To overtake an object far in front of you in orbit, you actually need to _brake_ - this will lower your orbit and you'll move faster. Then you need to re-boost your orbit for rendezvous. If you accelerate towards the object instead of braking, then you'll actually be moving _away_ from it (because you'll boost yourself to a higher orbit with a longer orbital period). 5) Astronauts might lose contact with Huston for a short time, but communication with the ISS and Shuttles is actually done through ground stations, not satellites. And suit radio is powerful enough that ground based amateur radio operators can actually tune and listen to it.

OK, these are minor details. Were they the only problems, I'd give this film 10 stars.

But I absolutely loathe the symbolics of this movie. It's anti-space and anti-intellectual. The whole movie tells you'll never live in space - it's sinister. It'll kill you. You only hope is to crawl back to Earth.

Technology is powerless. It can't even allow you to talk to your fellow humans on Earth. Your only hope is to believe in angels - you can talk with them.

The final scene is the most iconic - to reach the surface she actually had to shed all of the stuff touched by the space. The space suite was dragging her down. And in the one final attempt the parachute tried to engulf and drown her.

For this imagery and anti-progress attitude I give this film only 3 stars.
