Seen 30 of those.
Not sure if Repo Man really belongs in that (yes, I know, aliens, but I still never felt that as Science Fiction), but it's a great movie, so awesome. Same for Clockwork Orange. For some reason, I see those more as social commentary. Also, if they rate, so should Dr. Strangelove.
Starship Troopers does not belong anywhere near that list.
Also, pleased to see eXitance. Awesome movie.
Missing notables: Strange Days, Johnny Mnemonic, Interstellar, The Fifth Element, Equilibrium.
