Really Star Wars wasnt made for the kids to begin with, it was made for all audiences so kids could watch. It was ROTJ that started the trend of making it for kids, those damn Ewoks, followed by that stupid brat 10 yearold getting into the panties of a 14 year old Queen in TPM, with JarJar taking pictures *gar*
If you notice ROTJ and TPM are considered the worst of the series so far, even most classic Star Wars fans put AOTC above ROTJ, it was far darker and not so childish. Lucas allowed it to go chilidish because it makes more money, he lost intrest in telling the story.
Now read some of the early books, I think its Splinter of the Minds Eye, it was written after ANH and before ESB, its one adults will enjoy. Lets just say Luke and Leia get close, it doesnt come out and say it, but one can see where it seems as though brother and sister got "busy". I could even hear Star Wars sounding porn music starting up.
Now if Lucas went to make it for adults, Leia would probably have been topless in ROTJ, if Carrie Fisher would allow it. While on the topic of that sexy slave outfit (Considered borderline pornography in 1983) what was with Leia's stupid looking shoes? They look like something one would find on a Christmas Elf, she should have either been barefooted or wearing sandles like the Twilek girl was. I think that would have been more appropriate for a sexy slave outfit.
