And this was supposed to be a realistic movie?

Rating: 1/10 (22 February 2015)

What is a good way to start describing this awful movie? Sorry but I can't find the proper introduction, I would just say STAY AWAY FROM THIS!!!
I thought this was supposed to be a realistic description or presentation what happens if things to wrong in space, but if screenwriters and director spent 1% of the budget for consultation with physicist then things like sound in space, bouncing ball effects, explosions in vacuum wouldn't find the way into this movie. And lets not forget astronaut that's screaming like a young girl scared of a bee, who in the right mind would send into space someone so unreliable and unstable? I'm trying my best to figure out how is it possible that this catastrophe still has such a high mark, can someone explain this to me? Movie made in front of a green screen with 2 actors, bad acting and full of SGI gets so many nominations and then wins so many Oscars? HOW!?! Compared to this, movies like Armageddon and Deep Impact are masterpieces and are more realistic then Gravity. Hell didn't NASA?!? landed a unmanned space robe on a comet few months ago? Acting in this movie is bad, really bad, and if Sandra won the Oscar I would be 100% sure that ceremony now and 10-15 years ago is like comparing water and milk and its completely stages, as in judges are bribed. Really, who are the idiots in movie industry that decided to nominate and then give this movie so many Oscars?
I'm really sorry for people who haven't watched this movie yet and decide to do it, I truly am....
