I wish i would have avoided this movie....I love sci-fi movies and I'm a big fan of nolan. This is a long,time waster sci fi drama. the plot is really childish....how can nolan deliver this crap after he wrote inception?! the casting: with all the respect to mattew mcconau-gay...I'm not buying it, I'm buying it when you are a lawyer, a runaway criminal, a sick cowboy, even a officer on a submarine....but you are not a genius NASA astronaut material amigo! Ann Hathaway...her roll as the same drop tearing eyes drama queen bullshit is not necessary at all in this flick. Matt damon...i hope they paid you lots of money for your worst acting ever. now nolan, seriously,this movie published in almost every theater all over USA and the world, not in NASA scientists limited theaters. how do expect the common people that go to the theaters to understand half of the script in your movie? I just felt dumb, and i don't think I'm that stupid.I'm sorry but a movie stop being entertaining when you cant follow whats going on ,especially in this unrealistic plot . The entire movie extraordinary things happen and there is no explanation for any of it. I would never understand how a movie like this got 8.8 stars. while coppola's apocalypse now got 8.2 !? in short...don't watch it...not even on DVD, there is nothing to gain....there is 3 hours to lose!
