I mention this mainly because I doubted my memories when I saw the date 1984, which would have put me in uni rather than as still at school.
At that time, I was probably more of an arsehole than I am now, but I credit the film for making me rethink some really important things, mainly to do with rights/respect for others. I would like to think that its effect on me was positive.
At the time of watching it in the cinema (1982, with the explanatory voiceover "I knew the lingo, every good cop did" etc), I remember being uneasy with Deckhard's pressuring of Rachael to kiss him etc. But it didn't spoil the film for me.
Years later, I got a DVD collection with various cinematic releases and director's cut (without the voiceover narrative and with previously cut scenes) etc. I was surprised that the Deckhard/Rachael stuff hadn't been revisited; years after having watched it in the cinema, it looked to me to be even more like an abuse thing. However, I still rate the film for providing a slap in the face about discrimination etc.
I'd like to see another cut - with the voiceover, which helped me and I like it - but with revisions to the Rachael/Deckhard pressured relationship thing.
It isn't as though Harrison Ford hasn't had revisionists messing with his work, after all. We all know that Han shot first. ;-)
I recommend reading some of Philip K. Dick's works for more of that, which I would summarize as "what it is to be human".
In terms of visual spectacle, it may be tops. The detail and research highlighted by this 'coincidence':

I hadn't thought about it until now, but these days, science fiction and fantasy movies that end without everything exploding should get bonus points.
