I watched this again at the weekend - still a brilliant film, and could easily compete in the cinema as a new release, IMO.
As for the replicant issue - I watched the Director's Cut but although there is some innuendo, I really don't think there's anything that points to clear evidence.
The only attempt to really stake a claim is with the Unicorn scene tying up with the origami - but this seems more an attempt by the director to suggest a point, rather than the actual script. As has been mentioned in the other thread, there's a lot of symbolism involved around Unicorns, and the unicorn scene insertion I never felt really sat in the film.
Issues such as Deckard climbing with broken fingers I'd put down to just artistic licence - "heroes" traditionally do such feats - and Roy knowing his name as a continuity/scripting issue.
That there were 6 replicants, 1 died, and only 4 to hunt doesn't necessarily implicate Deckard IMO - it could even imply Rachel was the 6th. And if Deckard had been among them, why no apparent recognition from the hunted replicants if they should have known him?
Personally, I don't think the film can have so much impact if Deckard is a replicant - it's a classic "man vs machine" exploration as a theme, and Deckard as a replicant weakens that considerably.
Still, there's enough innuendo to suggest the possibility, the script itself never really tries to offer any real evidence, IMO - simply applying a more interesting ambiguity to open up the scope of the film to possibilities.
2c.
