One of the more underrated and important motion pictures of the late twentieth century is coming in a new director's final cut DVD in December. Ridley Scott is one of my favorite directors and this is Harrison Ford's best movie.
The Director's Cut (released in 1991) plays better in 2007 than the studio version did in 1982, and we have the benefit of retrospect in seeing the movie's influence--despite the pat 1982 happy ending (bolstered by outtake countryside scenes from Stanley Kubrick's The Shining)--on urban and cinematic culture in 25 years.
Oh, and now we see that Deckard is a replicant. Deal with the spoilage. If that had flown in 1982, it would have been at least the plot-twist-equivalent of Dr. Malcolm Crowe's realization in 1999.
