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.
But I think it's well regarded because of the world building, set design, costumes, and music.
