Thanks to membership rewards, I was able to purchase this dvd for $9.99 on sale. Normally, it would cost $24.99. However, I placed the dvd into my player and watched with great interest as I like actor, Matt Damon. The storyline was well written and kept my attention throughout the movie. A movie that shows the true spirit of survival when push comes to shove. A good movies for all fans Nasa and the exploration of space. Perhaps by 2030, we will be building cities with the very dirt of the moon or mars with 3D printers. Recommend for all individuals and families.
