after Clones I was on the fence about how good Sith would be. i was certainly into the trailer (i think all the prequel trailers set you up to expect a good movie).
however - the opening space battle felt soul-less and less dynamic than stuff in the OT (or, say, Starship Troopers) and i was facepalming by the time artoo was igniting fuel with his jets. the yoda/chewie relationship was getting too much etc.
i thought we'd see a lot more around hunting down the jedi, by vader personally rather than the directive 66 montage. the rise - and revenge - of the sith at a more personal level rather than clones doing the dirty work.
the backstory around how yoda arrived at dagobah is disappointing to say the least - was i watching ET for a moment there?!
i didn't think padme would die (though by that point in the movie it seems obvious) because leia has memories of her. there could've been a whole other emotional subplot around a mother giving up her babies and killing herself or whatever, but no.
the more i think about III the more i wonder how anyone can consider it top of the pile.
