Wow. You must have some kind of keen insight or something, because you nailed a lot here. It could be my age, not sure. I grew up in the 80's. I actually had to study this in film class in highschool, and I was so bored I fell in and out of sleep throughout the movie.
But I am well aware of Blade Runner's place in cinema, so I bought the steelbook in hopes that I would have a revelation if I watched it again.
I watched it alone, late night, with the lights off, and whiskey in my right hand. (I am not kidding - Jameson Irish Whiskey).
I think Harrison Ford is distractingly clumsy (I mean... he always is, but over the top in BR). When he's fighting Leon, he flings himself around like a ragdoll. It's really weird.
I actually really really wanted to like it. I tried. I promise. Someday I may take it up again.
Anyway thanks for your post. That was awesome
