The problem as I understand it is that there isn't a complete print of the movie in existance because it was severely edited when first released for the N. Am market and the cuts lost, so any "new re-release" is always going to be a compilation.
Last month our local community TV
station showed a version that sounds like the 80s one you have. The film is "shaded" with different colours "to reflect the atmosphere of each scene", or some such BS
. It had a modern soundtrack which wasn't too bad but when combined with obviously extended subtitles and dialog frames seemed to dumb down the whole effect and message. Like, we can't expect the audience to think for themselves so we have to explain it all to them.
However, quality of the actual shots was good compared to some very bad fragments I seen over the years. It also included still photos from the original inserted to replace missing edited out scenes which improved continuity and restored some completeness to the story.
Be interesting to see what this "new" release provides.
Whatever, it's still a great piece of cinema.
"Metropolis" and "Run Lola Run" great examples of German film making.
