Last time I saw it, it wasn't quite as good as I'd remembered, but still probably the most atmospheric movie I've ever seen. Is this a good time to bring up that Deckard is not a replicant and that dreaming about a unicorn could not, by any stretch of the imagination, signify that one is a replicant? Not only could anyone dream about a unicorn at any time, even if his dream is a flashback, he could easily have a genuine memory of a unicorn, since there's all that genetic engineering going on.
On my drive from Toledo to VA on Thursday, Terry Gross on Fresh Air interviewed Ridley Scott. He stated that Deckard is a replicant. It was unclear in the original version of the movie, but I certainly got the impression he was in the "director's cut" version.
