I saw Blade Runner 2049 recently. I have some (not very original) thoughts to share. Spoilers ahead.
The original Blade Runner only really caught my attention in my adult years. Unlike, say, Back to the Future, Ferris Bueller's Day Off and Superman, it was not one of my "childhood movies". I saw it once when I was very young, found it boring and weird, and then promptly forgot about it until I was made to watch it sometime in my 20's or 30's with my eyes fully open.
Once I did, though...wow. That movie drips atmosphere. I'd be lying if I said it's one of my favourite movies of all time - I feel like that kind of designation is less about the movie itself and more about my frame of mind at the time I see it - but it's definitely up there as one of the movies I admire most from a visual standpoint. It's still beautiful 35 years later.
