I agree. Deckard contemplating what it means to be human and finding solace in the very thing he is supposed to hunt and kill is far more interesting than ‘a replicant runs off with another replicant’.

Also, the unicorn scene can easily be interpreted differently. If people can except that Gaff read Deckard’s file and saw he dreams of unicorns then you can easily say that Gaff and Deckard read Rachel’s file and saw that she dreams of unicorns. Therefore the unicorn actually represents Rachel. Which kinda makes sense anyway.

After all, unicorns are a human invention and so are replicants. Rachel is discovering the world all over again, having realised she’s a replicant. She’s starting from scratch. Unicorns are a symbol of innocence and purity. A lot more appropriate as a symbol for Rachel than poor old, world-weary, borderline alcoholic Deckard 😉
