Blowing out skies, crushing blacks, and highly contrasted midtones are bad as they are good, and clearly are based by the person's intention of making a photo. For example, blowing a sky by a stop or two isn't going to kill you if you're capturing, say a landscape, but is completely unacceptable for a portrait as most of the contrast is lost on the face as well since the sky is on the same luminance as human skin. Opposite is true, if you are capturing a bird in movement, going a stop down will be beneficial for your sky, but you have probably crushed the blacks/shadows of a hawk in movement.
It's a scientific method.
