I was eleven that year. I was majorly hyped for the release, while I recall one of my friends dismissively saying, "I don't like his haircut."
Bought the Marvel comic adaptation. Loved it. Bought Do Androids Dream of Electric Sheep?, loved that. Went to E.T. with my brother, and was this close to sneaking into Blade Runner, but thought better of it (in those days, ushers would patrol the aisles and kick you out).
Missed it in the theatres, but saw it immediately when it came out on video in '83. So then, on top of the story, I got the music, I got the sound, I got the visual effects, I got it all, and I f**king loved it.
So even without having seen the film, I was captivated by Blade Runner, and I think that says a lot.
