One thing everyone forgets about Revenge of the Sith (which I suppose is fair enough, it was ten years ago) is how political and mildly controversial it was at the time.

When
reviews started coming out for it they all highlighted the point. The
Washington Post called the movie “a blistering critique of the war
in Iraq“, the New York Times reported that “Mr. Lucas is clearly jabbing
his light saber in the direction of some real-world political leaders”,
and Slant Magazine called it “an anti-Bush diatribe”. Even Hayden Christensen jumped in there and said the film was “absolutely” a shot at Bush and other US presidents, and George Lucas took some time out during the press tour to explain his thoughts on US foreign policy.

Some people went as far as to recommend a boycott. (It didn’t work, obviously) To this day
I’ve heard people say that Anakin’s line “If you’re not with me, you’re
my enemy” is lifted direct from a Bush speech – it’s not, but it’s very very close. People went wild about it.

ROTS was absolutely a movie of its time, and that time’s gone now, and time hasn’t exactly been kind to the movie either. But it seemed quite important way back then, and it’s definitely as, well, as angry as a Star Wars film ever got.
