a) poorly handled nuance, or
b) poorly handled superficial exposition.
Case in point: The contradictory argument that "Only Sith deal in absolutes." Is this supposed to be an indictment of the Jedi Order? Clearly, there are many parallels between the Jedi and the most odious and venal quasi-military groups today (recruiting children, religious indoctrination, use of force apart from legal authority). Was this the clincher, the final bit of proof we needed that Star Wars is morally relativistic and the Jedi are just as bad as the Sith?
On the other hand, George does not seem capable of such topical or profound statements. His latest hobby horse is the idea that Star Wars is a "Saturday morning serial," and anyone looking for a plot will be shot, etc.
Is George an inspired filmmaker who just isn't inspired enough to take a thematic stand, or is he a blind man wandering into a useful, if confused, narrative?
