I believe that the success of Lucas is tied into the pop cultural phenomenon that was the original Star Wars and Indiana Jones trilogy. He has gone back and tried to relive his glory days, instead of expanding and changing as an artist. While I did enjoy Indie 4, it is only a sequel that did not try to change the original movies that came before it. I enjoy it as a 1950's Indiana Jones Sci Fi flick, what I believe that Spielberg and Lucas were going for. Unlike the PT and SE, it has no effect to the established mythology. If you don't like it, don't watch it. The same cannot be said of Star Wars, since all we have are inferior versions of the great, forgotten originals. Micheal Jackson never made the original versions of Off The Wall, Thriller, or the Jackson 5 unavailable, even though he had moral and legal problems, he did not compromise his artistic credibility.
