Lucas Arts is just one of many SUBSIDIARIES of LucasFilms. He, strangly is the chairman of each of these companies, including ILM and others. Currently, while Disney is the owner, he STILL presides over LucasFilms as chariman and CEO and all the subsidiaries. Kennedy is slated to take over as chairman of LucasFilms, reporting to the CEO of Disney at some later date.
And everybody is entitled to their opinion on whether they are capable or responsible to direct someone else's vision in another direction. Many artists do that. Stephen King doesn't, Speilberg doesn't, the best minds usually don't consult with others. They may, as Lucas and Spielberg did or Hanks and Speilberg did, collaborate on projects. You miss the point, though. The creative product that springs forth from someone's mind is theirs and can't be wrong. You may dislike it, but it is, in this case, science-fiction, not science-fact.
I hear people say they walk out on movies, not because they are trash, but because of something in it that can't happen in real life. Well, no shit. it is a story just like Old Mother Hubbard. Who lives in a ****ing shoe? What boy can fly? Who can break into the CIA and dangle from a rope to break into a secure computer? The answer is nobody, until it hits film after coming from a creative mind.
