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.

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.
