You're right. I do feel that people have been overlooking that point. It certainly would have served to have had some people on board who had enough clout to challenge George. On the other hand, I can't say I disagree with the sentiment of letting "undiscovered talent" cut their teeth on these movies. It's certainly an opportunity anyone would jump at, and, just because they haven't become huge names yet doesn't necessarily mean that they wouldn't be able to turn in a good product. Again, think of the original effects crews for Star Wars. They were recent college graduates, people who'd done some effects work for commercials, who became the backbone for the original ILM. So while this tactic didn't do much to service these films, I certainly can't fault them for the idea.
