What goes around comes around. If you further darkness and taint youth--it'll come back to bite you. Ending the series glorifying darkness would be a real shame.

We may not be able to see it when it bites George, but rest assured it will and all the money in the world can't avert the simple principle of feedback.

Lucas merits a measure of compassion. After the first movie one assumed he was more talented/swift than he actually is. Each successive film proved that "Star Wars" was, by far, sheer luck mixed with a special effects edge for the mid-seventies, but not scripting skill. As a result everyone expected far more than he could deliver from subsequent films. That in itself has got to be a constant thorn in Luca's side.
