I checked rotten tomatoes again today, to see if there were any new reviews up. There are 2 new reviews, both bad (NY Times and Richard Roeper).
For those of you keeping score, it has dipped again to 18% for the T-Meter Critics (down from 19%) and is now at 4% for the Top Critics (down from 5%). http://www.rottentomatoes.com/m/clone_wars/?critic=creamcrop
