Science is cool. That is the idea that sits at the beating heart of The Martian. Without it nothing in this film works and yet it could have so easily been its downfall. Based on a book which tried it’s hardest to be scientifically accurate, The Martian may not have been the easiest conversion to the big screen. Science may be cool, but on a cinema screen it is rarely sexy. Yet somehow Drew Goddard’s script makes it not only work, but makes it sparkle. Throw in Ridley Scott doing his best work in years and The Martian may well be unmissable.
