Back on topic, as someone pointed out, Lucas didn't exactly say "screw you" to everyone & do his own thing on both STAR WARS & the prequels. Back in '77, even though he did basically say "screw you" to the studios in an effort to do his on thing, he still had mentors & trusted friends who challenged him & pushed him to do great things. Even though he was "doing his own thing" with the prequels, at that point he was surronded by "yes men" & would brush off anyone who questioned/challenged him.
