My top films would be
Bladerunner - if nothing else for Pris and Roy Baty’s Soliloquoy
Planet of the Apes - Ground breaking and very pro evolution
Star Trek - Wrath of Khan
Jurassic Park
Alien (even though it drifted far from the original ss in “Voyage of the Space Beagle)
Armageddon - based somewhat on something that could really happen
