It had been literally years for me too... was amazed how good it looked in BlueRay! Also I had originally remembered it (like I think you had) as the androids being evil, but I was alot younger when I saw it, and I think the original cuts didn't really convey what Ridley Scott wanted. I thought it was hilarious that Harrison Ford apparently purposely did a crappy job on his narration because he thought it was dumb to add to the movie.
