I completely agree, I feel that the makers of the Star Wars universe try to make it so that each book/movie is slightly different, but always come back to that theme good will triumph evil, even though that not might be how it happened in a specific part. That is why it is a saga. It's a continuing story about good vs evil. I feel that they could and may make another Star Wars movie, with Lucas at the head? Who knows. But with the current state of the Star Wars Universe it seems it's building towards something big.
