Grossly over-rated due to poor script

Rating: 4/10 (12 October 2015)

Background: I like sci-fi, and I like Sandra Bullock as a fun actress. And I respect films that attempt something.
So here, Gravity attempts, I think, to show us how even in mere low earth orbit, space is this hostile environment where a human life weighs nothing. OK.
So at first, big shower of space debris. Never mind that it half destroys a space shuttle, and sends it spinning, all the while not doing anything to Sandra and George. So then Sandra panics, fine as she's not an astronaut. And George comes to the rescue, OK a bit of a macho cliché but fine given the respective parts. So then George says they have to fly next door to the ISS. So they do. And guess what, they just just make it, as George runs out of fuel, and going too fast, so there's a miracle last second catch by dangling ropes. Hmm. And then once they have stopped, ie no more momentum, George decides that somehow the ropes are going to snap...and they start snapping! So he lets go of the rope - how very courageous and macho of him! So Sandra just barely manages to reach the hatch with her last breaths of oxygen. She then removes her space suit - how totally illogical. Then as she's attempting to radio someone, a fire bursts! But Sandra just barely manages to not get the least little burn even though she's wearing very little (and looking good). And she even manages to get to the Soyouz. Then she manages to separate the Soyouz from the ISS and tries to leave. But oh wait, the parachute is blocking her, and the ropes make the Soyouz bounce back towards the ISS! But Sandra just barely avoids the crash. Then she spacewalks to separate the parachute. And just at this moment the debris reappear. And they destroy the ISS and send it spinning - but somehow Sandra doesn't even get a tiny hole in her suit! So then Sandra aims at the Chinese space station. Then wants to get the engine started - but no fuel! So she despairs and lowers the O2 to commit suicide. So then miracle, she dreams of George and he tells her to try and to remember about the landing thrusters! So she un suicides, and manages to fly to the station. Apparently she aimed to well that she makes it at once! Of course upon arrival, she's going to fast, and she just barely catches the last possible handle. Of course. And it happens to be the hatch. Of course. Once in the station, and then in the Chinese Soyouz, she gets it separated, and they fall towards Earth. As they fall, the debris that left with her, somehow passes her! Finally she water lands. Pfew! But she's not done yet: she opens the hatch and water flows in! So she has to wait for the craft to sink about 50ft down, and then leave it! But with her suit she's too heavy! So she has to remove her suit and then swim to the surface! One more lucky escape! Then she swims a mere 10 seconds and already lands on the shore. And she looks up, and the debris that were passing her on the way down, are still flying up there!
BOTTOM-LINE: could have been GREAT about the fragility of human beings in space. Loses all credibility by adopting an unbelievable, Roger Moore in James Bond style of scenario, which would be amusing in its own right, but not in this film which tries to convey a serious message.
MARK: worth about 3 based on the script. I gave it 4 because of the visual effects.
