Unpopular opinions ahoy:
I watched Blade Runner for the first time about 8 years ago, and I felt - and still feel - that it just doesn't quite work. I can understand all the reasons it inspires such devotion; the performances are brilliant, the production design is phenomenal, the effects haven't aged at all and the music is perfect. The script just lets it down. My overriding feeling is that it simply elides too much; there's a thin line between being mysterious and being incoherent, and Blade Runner spends most of its running time on the wrong side of that line.
Blade Runner 2049, on the other hand, is a masterpiece, and easily one of my favourite films of recent times. It gets everything right that the first film did, but succeeds combining a stunning audio/visual experience with an expansive, emotional story.
