I just watched the "Final Cut" with the ambiguous ending of whether or not Rachel lives or dies....and the ambiguous insertion of a unicorn scene that wants to tell the audience that Deckard may or may not be a Replicant. (I'm okay with the ending, but I would rather the unicorn scene not be there....since that is an element not really followed up on in the film). There is a big plot hole that I found, however: If Rachel had been working with Tyrell, and he knew that replicants were illegal on Earth....why did he ask Deckard to perform the test to see if she was a replicant? Why was he allowing her to work for him knowing she would be in danger eventually? Note: I still have the original cut to watch again - I've not seen it for years - as well as the 'international' cut and 'director's cut.'
