Sorry, I didn't understand it couldn't be a franchise and only "hardcore" sci-fi movies.
Forgot about Gravity. Ten times better than The Martian. Add Sunshine to the list too. And maybe even Tomorrowland and Jupiter Ascending. And let's not forget about the excellent Moon. What about Oblivion? Pacific Rim? I'm very happy with the pace Hollywood cranking out good and decent sci-fi movies.
Well, I don't know what the heck your criteria is for good sci-fi movies cause I certainly think that is a solid list.
Out of curiosity, what do you think is a good movie to represent the sci-fi genre?
And frankly, how many sci-fi movies do you really expect Hollywood to churn out each year?
I think District 9 and Edge of Tomorrow are the best movies in that list.
