Just an ordinary mainstream Sci Fi flick

Rating: 6/10 (4 January 2016)

I honestly don't understand why this movie has such a high rating on IMDb at the moment – there is nothing outstanding about it at all.
Plot is primitive and predictable (one character says: 'but something could go wrong!' and in 10 seconds something wrong happens). There is no tension whatsoever even at the roughest moments of the movie – jokes keep flying around. The main character is obviously not afraid of anything and not going nuts because of social deprivation. Moreover, main character somehow carries expert knowledge beyond his competency (botany), beyond the job he was hired for.
There is not a single convincing character in the movie. Mars team looks like 'Avengers' – everybody is equally young and handsome, kind and brave, ready to lose their lives and jobs for abandoned colleague. Earth team makes jokes every opportunity – obviously they are not stressed at all. China joins for no reason at all (some old important Chinese guy decided to help an American astronaut, really?)
I would forgive the weakness of the story if the FX was amazing but it's not. While it's pleasant to watch, there is nothing new or groundbreaking.
In sum, it's just another mainstream Hollywood movie that should be rated 6 on IMDb. Current rating is misleading.
