i consider it a must-see clip of about 3 mins. batty the replicant, has defeated decker, the 'blade runner' who is assigned to terminate him. and now that decker is about to fall to his death, batty saves his life; and then the dialog. The dialog!
i have no idea what are "attack ships off the shoulder of orion" or "c beams on tannhauser gate", but it is a beautiful ending.
my favorite sci fi movies of all time:
1. 2001 a space odyssey
2. blade runner
oddly enough, in all three of them, the most sympathetic, 'human' character is a non-human: in 2001, the computer HAL who loses his mind, in blade runner, the replicant batty, and in solaris the sentient sea that's beaming hallucinogetic images into the spaceship that's bothering it.
