Here's a radical claim, from the _NY Times_ review,
by AO Scott:
"This is by far the best film in the more recent trilogy, and
also the best of the four episodes Mr. Lucas has directed.
That's right: it's better than 'Star Wars.'
'Revenge of the Sith' ranks with 'The Empire Strikes Back'
(directed by Irvin Kershner in 1980) as the richest and most
challenging movie in the cycle. It comes closer than any of
the other episodes to realizing Mr. Lucas's frequently
reiterated dream of bringing the combination of vigorous
spectacle and mythic resonance he found in the films of Akira
Kurosawa into American commercial cinema."
