What is this madness?

Rating: 1/10 (16 June 2014)

When scifi goes overboard with effects and monsters I'm fine with it. Very often realism isn't really part of the equation. But, Gravity presents itself as a movie that might be realistic. I'd peg Apollo 13 as its closest visual twin. With both the space shuttle, and Hubble, having roles in the movie, it's not set to some distant future. This collides head on with the writing, which is off the charts bad.
1. For some unexplained reason a medical engineer is repairing circuit boards on Hubble. 2. She refuses to stop working when ordered, in a life threatening situation, even though stopping would have no serious consequences at all. If lives were in the balance either way I might buy this scenario. 3. One of the astronauts is just randomly bobbing about in an EVA-suit, doing absolutely nothing but blabbering on about "a bad feeling about this mission" - followed by random anecdotes. Astronauts joyriding billion dollar equipment? I'm no astronaut, or NASA finance guy, but this seems far fetched. 4. During the entire first half of the movie the main character is completely helpless when stuff goes wrong. Prepared for nothing, and hyperventilating pretty much all the time - with 5% air left in her suit. It seems like NASA should let me into space. I wold be equally incompetent. 5. Russia shoots down its own satellite, instead of the tried and safe method of dropping them out of orbit to burn up in the atmosphere? 6. Space junk with the average speed of an 86 year old man in a wheelchair. 7. For some reason the Russian space station is full of vodka. 8. For some reason the Chinese space station has ping pong paddles flying around. 9. Airlock hatches explode open, potentially killing whoever is trying to open them. 10. Astronauts hanging on to the airlock hatches by the fingernails while they explode open. 11. The same astronaut(s) too weak to get on their feet in proper gravity - even if they displayed superhuman strength just minutes ago. Also after only a few days in space. 12. The escape pod immediately sinks after landing in water, even though heaps of re-entries are made into the ocean. I cannot remember ever hearing of one of them sink.
I don't usually get worked up over logical flaws in movies. Most of them slip by me unnoticed. But this was 90 minutes of purebred annoyance. Not one single thing about it seemed realistic, or even slightly plausible.
The visuals are pretty, and technically it's well made. Clooney is his normal, charming self - but when the writing is this bad, it just doesn't help.
How this thing won several Oscars, and has an 8.1 IMDb rating, is incomprehensible to me.
