I had my set calibrated this morning by Steve from smartcalibration.com and have spent the day going through all of my Blu-rays and what a difference it has made.
Apparently the blue was really screwed up (waaaay too high) from the factory so the colors were really off. Now, after the calibration, everything looks so much better and so much crisper.
BHD looks even better now
To paraphrase Ferris Bueller, "It is so choice; if you have the means, I highly recommend getting it done."
