I think this was one of the greatest science friction film.and every actor doing a great job.mainly Matt Damon, and what a thought! everything in this movie are realy great like cinematography, casting, sound, graphics . when every astronaut go from mars and only matt damon are present in the mars it was best part of the film. after seen this film I say only one word wow.Director Ridley Scott do a great job .when I seen this film I can be imagine this realy happens in the world and NASA space station in this film are like a original NASA space station. who love watching science friction film THE MARTIAN is the best gift for him.friends just see the film and enjoy the Mars atmosphere.
