Very disappointing.

Rating: 4/10 (17 June 2012)

I've given 4 only for the impressive visuals in the movie.
As for the rest... the science is consistently nonsense, the Christian religious references make no sense in the context of Christianity. The creationism vs evolution references are lame and philosophically weak, un-thought-through and poorly presented. The acting is so so and does nothing to save the story, which is dull and unimaginative.
A few specifically ridiculous things...
Why hire such a pair of twits as the geologist and the biologist for such an expensive and important mission? Did they ask for volunteers at the unemployment office? Come to that, how could they have such a crew of unprofessional clowns for a $1 trillion mission?
Can a surgery be any more ridiculously fake? Spray on a bit of "anaesthetic" and perform a Caesarian on a struggling woman?
How can there be such a powerful storm of such large particles and no- one's suits or helmets have any real damage? And there isn't piles of the stuff building up everywhere? Did it evaporate?
I suppose David's ability to read and speak a 2000 year old language isn't 'too' ridiculous, though it is still ridiculous.
To enjoy this movie one must have to a good level of scientific and religious illiteracy, or an exceptional ability to suspend belief and ignore the silliness of the whole thing.
And the attempt to link it to Alien was pathetic. To compare the movie to Alien at all is an insult to a true classic and that they'd make such a poor movie today with its big budget should be an embarrassment to its makers.
Disappointed.
