Having recently moved to France, I have just seen the new version of Legend with Jerry Goldsmith's soundtrack, and thought I was watching the wrong film! I have loved this film since the time I first saw it in the States ages ago - and have been a fan of Tangerine Dream's since the 70's - but, in my humble opinion, the new soundtrack just doesn't work for this film.
Mr. Goldsmith's music certainly is quite lovely, but Tangerine Dream's music captured the essence of the film's story perfectly. To add insult to injury, there's no Bryan Ferry at the end of the new version, and that's one of the best parts of the whole movie and soundtrack!!! That alone makes the new soundtrack quite a letdown, I urge anyone looking for a great ambient soundtrack to buy this version!!!
I realize that directors are allowed their artistic differences with the studios, and firmly believe they should be entitled to issue their own cuts, but they might also remember that fans usually like the work they originally saw and heard.
