There are thousands of people who gonna tell you that there are many fake or unreal scenes. But I want to tell you that just see the spirit of Mark Wateny to be alive. He, his crew and NASA done a remarkable thing. Story is full of spirit, emotions and dedication.
There are many difficulties around Mark but he become a superman. How he came back from mars is a phenomenal job. We think they did many mistakes but we dont know about space that is why we saying this. Just enjoy the movie. Get inspired.
