Strap in for a trip to Mars! Two of them, actually (well... four, if you want to get really technical), as Scott and Steven tackle Brian De Palma's theme-park-ride-based yawnfest Mission to Mars (2000) and the terrifically intense Ridley Scott space adventure The Martian (2016). 
Which movie gets the science right? And which one is as dull as it is silly? The answers may surprise you. But probably not.
