Matt Damon or not, FREAKING OUTSTANDING film. Howard Tayler (of Schlock Mercenary fame) said of it,
I'm now declaring that The Martian, (movie) is the best hard science fiction movie I have ever seen. It is not a perfect film, but it is an outstanding film that speaks the way only a film can, and uses the medium in ways that the very best films do.I concur.
I will be seeing it on the big screen again.
