I loved the movie, mostly because it dealt with topics that I am very interested in. Space exploration is just.. Awesome. I think this movie was aimed in a very great direction and was executed well; however, in areas it seemed to show that it was lacking power of a bigger budget. At other times that is not the case at all, As there are many great visual scenes, and a fantastic conclusion.
I think the acting was very unexpectedly good, not a single person was a bit unbelievable or annoying or anything like that.
The story is great, and is very much intelligently woven with modern theories and discoveries in science.
There is one thing I will say in a somewhat negative vein. There are certain kinds of scenes that I wish they did way more of, like outside on the planet. Not that they don't do it enough, but you can never have enough of that.
I highly recommend this to any sci fi/ space fanatics
It is one of my favorite movies in the last couple years.
Hope you enjoy it.
