Saw it last night and found it predictable and over rated and actually annoying.
Ok
This is supposed to be a really grounded scientific movie, right, but started so badly: The Martian atmosphere is 1% the pressure of earth, it's like a vacuum. So the storm, walking in a storm that can tip rockets over, and sealing tons of earth pressure in the Hab with plastic, that then flaps in the storm makes NO SENSE.
My 6 year old son said after the movie: how come sometimes he bounced like he was on the moon, and sometimes walked like it was normal earth gravity?
There was other stuff as well, from coms, to botany, and they kept piling up and taking me out of it.
Why sit in a freezing super computer centre with a laptop? because massive computer racks look cool on a big screen? Ok that's lame too.
I can gloss over some cracks of the type in (say) interstellar Or gravity but for a "science the shit out of it" movie these cracks were too big for me anyway.
