I'm not sure I follow, The Martian is about one guy stuck on mars completely alone, and there is no aliens as in Mission to Marse, or save the earth thing as in Red planet, just an ordenary mission gone wrong. It also strives for realism, even though i know experts have criticised some of it. Sure they all take place on Mars, but i find them very very different. Enjoyed Mission to Mars for the first time a couple of months ago, and wouldnt describe it as a good movie, but it kept me entertained. Guess I have to watch Red Planet too.
