MOVIES

The only reason to catch Harrison Ford, Rutger Hauer and Sean Young in the original 1982 version of “Blade Runner” (9 p.m. USA) is so that you might further appreciate Ridley Scott’s vastly superior 1993 director’s cut of this dense, dark science-fiction fable, based on a novel by Phillip K. Dick.
