Agree with the conclusion, tough not with all of your rant.
The movie was good, no doubt, but there where obvious sacrifices made so the masses can eat it up. It was one of the better tragedy/sci-fi movies of the past years, tough there where plenty smaller ones that were superior, but the media completely ignored it (Europa Report anyone?).
Never the less, the acting was believable, the suspense was there and visually it was stunning, even by not making it an overkill. Solid flick, and it made me look into the directors older works.
