You probably know this but the "original" version had his voice over which I liked, everyone else complains about this gave an idea of who Dekkard was and what had gone before to get where he was now. I saw this in the cinema when it first came out and though a good movie I was in my early teens I felt it was a little to slow at the time , I have seen 2 other releases at the cinema the final one about 2 years ago and it blew me away it really needs to be seen in the cinema to be appreciated and with out the voice over I found to have completely different character, I found myself not liking him at all which was great . I still dont no if if is a replicant or not , I never thought he was when it originally came out. What ever version you see its an experience that I dont think there will ever be another film quite like Bladerunner its depiction of the future as bleak as it is, is as realistic as anything you might see, Enjoy
