Re: So I read it
Personally, i prefer the original version. Sure the voice over's a little goofy, but so is Harrison Ford. The happy ending doesn't match the rest of the movie's tone at all but i like it anyway.
Gaff has this origami fetish. Cool. So at the end he leaves a unicorn for Deckard because he found out that Rachael is special, no 4yr life span. She's unique, like a unicorn. He knows Deckard and Rachael are going to make a run for it and he lets them. End of story. To me there's no need to add all this 'it's from Deckard's dreams' crap.
BTW, did you know Ridley Scott shot this commercial in 1979 using music by... Vangelis.
