That's about the only instance in which it could be considered 'dark', but yeah, it's a great example of how it could be done. The other times the theme is used in a minor mode are always used as a specific motif for Luke: - SW/ANH - introduction to Luke on Tatooine - ESB - introduction to Luke on Hoth - ESB - Luke's arrival at Bespin - ROTS - baby Luke is delivered to the Lars homestead (Pretty sure there's a couple of others) It may have been possible to work the theme into the Anakin reveal in ROTJ, rather than the beautifully sad rendition of the Imperial March, as that could have cemented it as the 'Skywalker Theme' rather than Luke's. At that time, however, a Prequel Trilogy was the furthest thing from GL's mind, he just wanted it all over. I absolutely adore the treatment of the Imperial March in that scene, anyway. The theme does occur throughout the Saga in its more bombastic 'action' version, however, and doesn't necessarily include Luke (although it usually does). IIRC, in an old discussion on the topic, someone cited an instance(s) in TPM and/or AOTC.
