I would be okay with the V.O. narration if Ford hadn't
done such a crappy job on it - deliberately crappy or not.
I always visualized Deckard as a HUMAN Philip Marlow sort
of character. I have always had distaste for Ridley's Deckard
is replicant conceit. I feel he thought it was a clever and
unique gimmick.
"Look how avante garde I am everybody!"
I'd like to lock Ford in a room now, 30 years
later, and have him try that world weary dialogue
one more time.
