It was one of those movies where the audience actually applauded at the end. I thought it was extremely well done -- compelling story, great acting, phenomenal FX. Ridley Scott made a great movie. The one scene that really shocked and made me question the science behind it was when they used a parachute to cover the open nose cone of a rocket for a space launch from Mars. Is that really possible? Mars has an atmosphere, wouldn't anyone inside the capsule be killed?
