I DON’T AGREE with a number of entries on this list; Blade Runner at No. 2 is not only NOT one of the greatest sci-fi films ever made, but not even a good movie. In fact, it is a very weak movie which I would never recommend to anyone, except as a case study in overrated movies.
On the other hand, I do agree that many of the films on the list deserve to be there. Notably, 2001 is easily the best sci-fi film ever made, and Gattaca is rightly high on the list. Placing Aliens ahead of the original Alien makes no sense, however — Aliens is probably the worst of the 3 sequels. And Mad Max is hardly sci-fi. Overall though it’s not a bad list. Your thoughts…?
