SPOILERS FOLLOW.
i'm definitely on the director's cut side of things. the narration was a device which played on the film's
noir roots (and this film, effectively (though chinatown can stake a large claim too), started the 'neo-
noir' cycle, including films like dark city and the matrix, amongst others) - most films
noir of the fifties employed this 'hardboiled' narration (from their near-exclusively male, detective protagonists) style to create a more tangible sense of mystery and investigation (and it was also thought to help ease the relationship between the films and their, mostly, original book forms). i guess it just followed on that a 'new'
noir film would employ the same techniques.
regardless, and like others here have already said, it doesn't work in this film at all. but it's not the narration that bothers me so much: like chupu and fairnymph note, the idea that deckard is a replicant (and yes, he
is) is only followed through to its logical degree in the director's cut. considering it's one of the more interesting philosophical ideas of the film, i find it rather stupid that it was ever left by the wayside.
i also abhor the 'happy ending' with deckard and rachel leaving together: it doesn't fit at all with the mood of the film, and feels - as it was - like a badly tacked on ending to appease an audience that didn't, at the time, give two shits about the film anyway (it only came to critical acclaim many years later).
great film though
