Obviously not a mind blowing suggestion and cinemaphiles will recoil at the idea but have you tried watching it at 1.5 speed?
I watch some stuff like this because while the Directors vision might require 3 breaths to get the point across I am happy to accept the premise being suggested in 3 seconds. Cinema is a communication medium, not a recreation or simulation of events.
It's a boring movie. It's not a very good plot (and even has some weird coincidental plot holes).
But I think it's well regarded because of the world building, set design, costumes, and music.
Spot on. Not a movie to watch for the plot. True to the source in this. With Philip K. Dick's novels, reading for the "story" alone is totally missing the point.
Same for the Prime TV series, The Man in the High Castle. Again, true to the source in that the plot is moth-eaten lacework, but who cares? The world-building is great.
To be fair I don't watch movies / TV shows often because I have a low attention span for this stuff, but this is a movie I really wanted to like because I love the genre, but it's too slow paced for me. I do know that pacing was generally slower in older movies (eg. I recently watched "Roman Holiday" because so many older people love that one, and found it incredibly slow).
