Blade Runner
They don't make 'em like they used to. Sort of. According to Wikipedia, there are seven different versions of Blade Runner, from a 113-minute workprint version shown to test audiences in early 1982 to the "Final Cut" supervised by director Ridley Scott and released in late 2007. I saw the latter version1 and with the exception of Rachael's giant shoulder pads and the slower pacing, the whole thing seemed surprisingly contemporary (or not-too-dated at least). The film has aged well, like a fine wine.
