The newly restored version, which I saw recently thanks to a torrent, is a much, much better movie (both finer as an art work and more entertaining) than the truncated, barely coherent, version that I remember from being in film school in the 1980s. The restored version displays a richness and fullness of story line that the truncated version, which circulated for decades, only hints at. (Personally, I consider the Moroder version to be a true esthetic atrocity, not worth watching.)
