Yes. I have a couple of calibration DVD's for my home theater, and they all recommend turning the sharpness all the way down to the minimum, or one above the minimum if the lowest setting introduces excessive blurriness (this is rare from what I gather). The sharpness setting is a holdover from very old tv sets, and in most cases anything above the minimum actually ADDS noise around edges on the picture to "enhance" them. Any TV made within the last 15-20 years or so has a sharp enough picture that these enhancements aren't necessary and are actually detrimental to the picture.
