As a viewer - watching in high definition, I really liked the blue.
As a player - I can see why some where bothered with how slippery the court was. It certainly played too fast for the traditional clay court players who run around backhands and try to defend more than become agressive.
It is a shame they didn't handle the court set up better - they had to know there was going to be more scrutiny because of the color change.
Maybe it was just the microphones on court level, but to me when I heard the servers bouncing the ball in preparation to serve - the sound really seemed like it was an indoor carpet/court.
