The Martian takes Robinson Crusoe to a new level; and the whole "last person left on the planet" bit too. But unlike Robinson Crusoe who has no communications back home; Matt Damon's Mark Whatney manages to rig up an old rover; and thus make his life a lot better and easier. So, instead of a showcase on the descent to madness; it becomes a tale of scientific ingenuity and off course the inevitable rescue mission to end all rescue missions.
It is not as spectacular as gravity - but the individual performances are as good. The script and story is not as wild as Interstellar; but it's still as good. It was more practical; more feel good and something that highlighted both the dangers and need for space travel.
